   Modulated bimaximal neutrino mixing

   Subhankar Roy🇮🇳 · N. Nimai Singh🇮🇳

   The present article is an endeavor to look into some fruitful frameworks based on "Bi-maximal" neutrino mixing, from a model independent stand. The possibilities involving the correction or attenuation of the original BM mixing matrix, followed by GUT-inspired charged lepton correction are invoked. The "symmetry-basis" thus constructed, accentuates some interesting facets such as: a modified QLC relation, ${\theta }_{12}+{\theta }_c\approx \frac{\pi }{4}-{\theta }_{13}\cos (n\pi -{\delta }_{CP})$, a possible link up between neutrino and charged lepton sectors, ${\theta }_{13}^{\nu }={\theta }_{12}^l\sim \mathcal{O}({\theta }_C)$ or that between neutrinos and quarks, ${\theta }_{13}^{\nu }={\theta }_C$. The study vindicates the relevance of the Bi-maximal mixing as a first approximation.

   Flat Directions and Leptogenesis in a "New" $\mu \nu$SSM

   M. C. Rodriguez🇧🇷 · I. V. Vancea🇧🇷

   In this paper, we give a brief review of the Minimal Supersymmetric Standard Model (MSSM) and "$\mu$ from $\nu$" Supersymmetric Standard Model ($\mu \nu$SSM). Then we propose a generalization of $\mu \nu$SSM in order to explain the recent ATLAS, CMS and LHCb results. This "new" $\mu \nu$SSM generalizes the superpotential $W_{suppot}$ of $\mu \nu$SSM by including two terms that generate a mixing among leptons, gauginos and higgsinos while keeping the charginos and neutralinos masses unchanged. Also, it is potentially interesting for cosmological applications as it displays flat directions of the superpotential and a viable leptogenesis mechanism.

   On the Higgs cross section at N${}^3$LO+N${}^3$LL and its uncertainty

   Marco Bonvini🇬🇧 · Simone Marzani🇺🇸 · Claudio Muselli🇮🇹 · Luca Rottoli🇬🇧

   We consider the inclusive production of a Higgs boson in gluon-fusion and we study the impact of threshold resummation at next-to-next-to-next-to-leading logarithmic accuracy (N${}^3$LL) on the recently computed fixed-order prediction at next-to-next-to-next-to-leading order (N${}^3$LO). We propose a conservative, yet robust way of estimating the perturbative uncertainty from missing higher (fixed- or logarithmic-) orders. We compare our results with two other different methods of estimating the uncertainty from missing higher orders: the Cacciari-Houdeau Bayesian approach to theory errors, and the use of algorithms to accelerate the convergence of the perturbative series. We confirm that the best convergence happens at ${\mu }_R={\mu }_F=m_H/2$, and we conclude that a reliable estimate of the uncertainty from missing higher orders on the Higgs cross section at 13 TeV is approximately $\pm 4$%.

   Simplified Models vs. Effective Field Theory Approaches in Dark Matter Searches

   Andrea De Simone🇮🇹 · Thomas Jacques🇮🇹

   In this review we discuss and compare the usage of simplified models and Effective Field Theory (EFT) approaches in dark matter searches. We provide a state of the art description on the subject of EFTs and simplified models, especially in the context of collider searches for dark matter, but also with implications for direct and indirect detection searches, with the aim of constituting a common language for future comparisons between different strategies. The material is presented in a form that is as self-contained as possible, so that it may serve as an introductory review for the newcomer as well as a reference guide for the practitioner.

   Effective Majorana neutrino decay

   Lucía Duarte🇺🇾 · Ismael Romero🇦🇷 · Javier Peressutti🇦🇷 · Oscar A. Sampayo🇦🇷

   We study the decay of heavy sterile Majorana neutrinos according to the interactions obtained from an effective general theory. We describe the two and three-body decays for a wide range of neutrino masses. The results obtained and presented in this work could be useful for the study of the production and detection of this particles in a variety of high energy physics experiments and astrophysical observations. We show in different figures the dominant branching ratios and the total decay width.

   Dissipative Effect in Long Baseline Neutrino Experiments

   Roberto L. N. Oliveira🇧🇷

   The propagation of neutrinos in long baselines experiments may be influenced by dissipation effects. Using Lindblad Master Equation we evolve neutrinos taking into account these dissipative effects. The MSW and the dissipative effects may change the probabilities behavior. In this work, we show and explain how the behavior of the probabilities can change due to the decoherence and relaxation effects acting individually with the MSW effect. A new exotic peak appears in this case and we show the difference between the decoherence and relaxation effects in the appearance of this peak. We also adapt the usual approximate expression for survival and appearance probabilities with all possible decoherence effects. We suppose the baseline of DUNE and show how each decoherence parameters change the probabilities analyzing the possible modification using numeric and analytic approach.

   Revisiting the texture zero neutrino mass matrices

   Madan Singh🇮🇳 · Gulsheen Ahuja🇮🇳 · Manmohan Gupta🇮🇳

   In the light of refined and large reactor mixing angle ${\theta }_{13}$, we have revisited the texture three and two zero neutrino mass matrices in the flavor basis. For Majorana neutrinos, it has been explicitly shown that all the texture three zero mass matrices remain ruled out. Further, for both normal and inverted mass ordering, for the texture two zero neutrino mass matrices one finds interesting constraints on the Dirac-like CP violating phase $\delta$ and Majorana phases $\rho$ and $\sigma$.

   On the origin of the discrepancy between the expected and observed results at KamLAND

   L.M. Slad🇷🇺

   After a logically clear and simple solution of the solar neutrino problem on the basis of the hypothesis about the existence of a new interaction involving electron neutrinos and nucleons, the question arose about the origin of the distinction between the expected and observed results of the experiment with reactor antineutrino at KamLAND. In the present work, a significant attenuation of light during its propagation in the KamLAND liquid scintillator is noted, the effect of which on the observability of the expected inverse beta-decay events and on the reconstruction of their characteristics has not been adequately analyzed. Because of this, we do not consider the declared results of the KamLAND experiment as reliable.

    A global fit of the $\gamma$-ray galactic center excess within the scalar singlet Higgs portal model

    Alessandro Cuoco🇩🇪 · Benedikt Eiteneuer🇩🇪 · Jan Heisig🇩🇪 · Michael Krämer🇩🇪

    We analyse the excess in the $\gamma$-ray emission from the center of our galaxy observed by Fermi-LAT in terms of dark matter annihilation within the scalar Higgs portal model. In particular, we include the astrophysical uncertainties from the dark matter distribution and allow for unspecified additional dark matter components. We demonstrate through a detailed numerical fit that the strength and shape of the $\gamma$-ray spectrum can indeed be described by the model in various regions of dark matter masses and couplings. Constraints from invisible Higgs decays, direct dark matter searches, indirect searches in dwarf galaxies and for $\gamma$-ray lines, and constraints from the dark matter relic density reduce the parameter space to dark matter masses near the Higgs resonance. We find two viable regions: one where the Higgs-dark matter coupling is of $\mathcal{O}(10^{-2})$, and an additional dark matter component beyond the scalar WIMP of our model is preferred, and one region where the Higgs-dark matter coupling may be significantly smaller, but where the scalar WIMP constitutes a significant fraction or even all of dark matter. Both viable regions are hard to probe in future direct detection and collider experiments.

    750 GeV Diphoton Resonance in Warped Geometries

    JoAnne L. Hewett🇺🇸 · Thomas G. Rizzo🇺🇸

    We examine the scenario of a warped extra dimension containing bulk SM fields in light of the observed diphoton excess at 750 GeV. We demonstrate that a spin-2 graviton whose action contains localized kinetic brane terms for both gravity and gauge fields is compatible with the excess, while being consistent with all other constraints. The graviton sector of this model contains a single free parameter, once the mass of the graviton is fixed. The scale of physics on the IR-brane is found to lie in the range of a $\sim$ few TeV, relevant to the gauge hierarchy. There remains significant flexibility in the coupled gauge/fermion KK sectors to address the strong constraints arising from precision measurements.

    Prospects for Reconstruction of Leptonic Unitarity Quadrangle and Neutrino Oscillation Experiments

    Surender Verma🇮🇳 · Shankita Bhardwaj🇮🇳

    After the observation of non-zero ${\theta }_{13}$ the goal has shifted to observe $CP$ violation in the leptonic sector. Neutrino oscillation experiments can, directly, probe the Dirac $CP$ phases. Alternatively, one can measure $CP$ violation in the leptonic sector using Leptonic Unitarity Quadrangle(LUQ). The existence of Standard Model (SM) gauge singlets - sterile neutrinos - will provide additional sources of $CP$ violation. We investigate the connection between neutrino survival probability and rephasing invariants of the $4\times 4$ neutrino mixing matrix. In general, LUQ contain eight geometrical parameters out of which five are independent. We obtain $CP$ asymmetry($P_{{\nu }_f\to {\nu }_{f^{\prime }}}-P_{{\bar{\nu }}_f\to {\bar{\nu }}_{f^{\prime }}}$) in terms of these independent parameters of the LUQ and search for the possibilities of extracting information on these independent geometrical parameters in short baseline(SBL) and long baseline(LBL) experiments, thus, looking for constructing LUQ and possible measurement of $CP$ violation. We find that it is not possible to construct LUQ using data from LBL experiments because $CP$ asymmetry is sensitive to only three of the five independent parameters of LUQ. However, for SBL experiments, $CP$ asymmetry is found to be sensitive to all five independent parameters making it possible to construct LUQ and measure $CP$ violation.

    Inclusive three jet production at the LHC as a new BFKL probe

    F. Caporale🇪🇸 · G. Chachamis🇪🇸 · B. Murdaca🇮🇹 · A. Sabio Vera🇪🇸

    We discuss recently proposed observables, sensitive to BFKL dynamics, in the context of multijet production at the large hadron collider (LHC). In particular, we consider ratios of azimuthal angle differences in final states with three jets, well separated in rapidity from each other, with two of them being very forward/backward and the third one in the central region.

    Update on 750 GeV diphotons from closed string states

    Luis A. Anchordoqui🇺🇸 · Ignatios Antoniadis🇫🇷 · Haim Goldberg🇺🇸 · Xing Huang🇹🇼 · Dieter Lust🇩🇪 · Tomasz R. Taylor🇺🇸

    Motivated by the recent update on LHC searches for narrow and broad resonances decaying into diphotons we reconsider the possibility that the observed peak in the invariant mass spectrum at M_{\gamma \gamma} = 750 GeV originates from a closed string (possibly axionic) excitation \varphi (associated with low mass scale string theory) that has a coupling with gauge kinetic terms. We reevaluate the production of \varphi by photon fusion to accommodate recent developments on additional contributions to relativistic light-light scattering. We also study the production of \varphi via gluon fusion. We show that for both a narrow and a broad resonance these two initial topologies can accommodate the excess of events, spanning a wide range of string mass scales 7 \alt M_s/TeV \alt 30 that are consistent with the experimental lower bound: M_s > 7 TeV, at 95% CL. We demonstrate that for the two production processes the LHC13 data is compatible with the lack of a diphoton excess in LHC8 data within \sim 1\sigma. We also show that if the resonance production is dominated by gluon fusion the null results on dijet searches at LHC8 further constrain the coupling strengths of \varphi, but without altering the range of possible string mass scales.

    Moduli mediation without moduli-induced gravitino problem

    Kensuke Akita🇯🇵 · Tatsuo Kobayashi🇯🇵 · Akane Oikawa🇯🇵 · Hajime Otsuka🇯🇵

    We study the moduli-induced gravitino problem within the framework of the phenomenologically attractive mirage mediations. The huge amount of gravitino generated by the moduli decay can be successfully diluted by introducing an extra light modulus field which does not induce the supersymmetry breaking. Since the lifetime of extra modulus field becomes longer than usually considered modulus field, our proposed mechanism is applied to both the low- and high-scale supersymmetry breaking scenarios. We also point out that such an extra modulus field appears in the flux compactification of type II string theory.

    ${\rm Y}(6S)$ and triangle singularity in $e^{+}{e}^{-}\to B_1(5721)\bar{B}\to Z_b(10610)\pi$

    A.E. Bondar🇷🇺 · M.B. Voloshin🇺🇸

    We discuss the possibility that production of final states with bottomonium and light mesons at the peak ${\rm Y}(6S)$ in the $e^{+}{e}^{-}$ annihilation at approximately 11.00 GeV is in fact due to a triangular singularity at the threshold of the heavy meson pair production $B_1(5721)\bar{B}+c.c.$ through the process $e^{+}{e}^{-}\to B_1(5721)\bar{B}\to Z_b(10610)\pi$. The presence of the hidden-bottom resonance $Z_b(10610)$ then explains the observed enhanced production of the final channels with both ortho- and para- bottomonium states, ${\rm Y}(nS)\pi \pi$ and $h_b(kP)\pi \pi$. The discussed mechanism also predicts a distinct pattern for production of hidden-bottom states at the ${\rm Y}(6S)$ energy that can be tested by experiment.

    Sbottoms of Natural NMSSM at the LHC

    Jyotiranjan Beuria🇮🇳 · Arindam Chatterjee🇮🇳 · AseshKrishna Datta🇮🇳

    Search for the bottom squarks (sbottoms) at the Large Hadron Collider (LHC) has recently assumed a heightened focus in the hunt for Supersymmetry (SUSY). The popular framework of the Next-to-Minimal Supersymmetric Standard Model (NMSSM) could conceive a naturally light sbottom which could easily be consistent with available constraints from the experiments at the LHC. Phenomenology of such sbottoms could in principle be as striking as that for a light top squark (stop) thanks to a rather nontrivial neutralino sector (with appreciable mixing among the neutral higgsinos and the singlino) that the scenario gives rise to. Nonetheless, finding such sbottoms might require a moderately large amount of data ($\sim 300$ ${\text{fb}}^{-1}$) at the 13 TeV run of the LHC. A multi-channel analysis establishing a generic depletion of events in the usual $2b$-$jets$ +${\text{E}}_T$ final state while registering, in conjunction, characteristically significant rates in various multi-lepton final states accompanied by $b$-$jets$ might point not only to the presence of light sbottom(s) but could also shed crucial light on their compositions and the (singlino) nature of the lightest SUSY particle (LSP).

    The phenomenology of trapped inflation

    Lauren Pearce🇺🇸 · Marco Peloso🇺🇸 · Lorenzo Sorbo🇺🇸

    Trapped inflation is a mechanism in which particle production from the moving inflaton is the main source of friction in the inflaton equation of motion. The produced fields source inflaton perturbations, which dominate over the vacuum ones. We employ the set of equations for the inflaton zero mode and its perturbations which was developed in the original work on trapped inflation, and which we extend to second order in the perturbations. We build on this study by updating the experimental constraints, and by replacing the existing approximate solutions with more accurate ones. We obtain a different numerical value for the amplitude of the scalar power spectrum, and a parametrically different result for the bispectrum. This has implications for the allowed region of parameter space in models of trapped inflation, and for some of the phenomenological results obtained in this region. The main results in the allowed region are the following: monomial inflaton potentials, such as $V\propto \phi ,{\phi }^2$ can be compatible with the data, and (in a portion of the allowed region) the inflaton can be sub-Planckian over all the "observable" stage of inflation; gravitational waves from this mechanism are too small to be observed in the foreseeable future; a non-gaussianity parameter $-60<f_{\mathrm{NL}}<-20$ is obtained in the allowed region for exactly equilateral configurations, with a mild dependence on the parameters of the model and of the inflaton potential.

    Dark matter annihilation and decay from non-spherical dark halos in the Galactic dwarf satellites

    Kohei Hayashi🇯🇵 · Koji Ichikawa🇯🇵 · Shigeki Matsumoto🇯🇵 · Masahiro Ibe🇯🇵 · Miho N. Ishigaki🇯🇵 · Hajime Sugai🇯🇵

    The dwarf spheroidal galaxies (dSphs) in the Milky Way are the primary targets in the indirect searches for particle dark matter. To set robust constraints on candidate of dark matter particles, understanding the dark halo structure of these systems is of substantial importance. In this paper, we first evaluate the astrophysical factors for dark matter annihilation and decay for 24 dSphs, with taking into account a non-spherical dark halo, using generalized axisymmetric mass models based on axisymmetric Jeans equations. First, from a fitting analysis of the most recent kinematic data available, our axisymmetric mass models are a much better fit than previous spherical ones, thus, our work should be the most realistic and reliable estimator for astrophysical factors. Secondly, we find that among analysed dSphs, the ultra-faint dwarf galaxies Triangulum II and Ursa Major II are the most promising but large uncertain targets for dark matter annihilation while the classical dSph Draco is the most robust and detectable target for dark matter decay. It is also found that the non-sphericity of luminous and dark components influences the estimate of astrophysical factors, even though these factors largely depend on the sample size, the prior range of parameters and the spatial extent of the dark halo. Moreover, owing to these effects, the constraints on the dark matter annihilation cross-section are more conservative than those of previous spherical works. These results are important for optimizing and designing dark matter searches in current and future multi-messenger observations by space and ground-based telescopes.

    Observational constraints and differential diagnosis for cosmic evolutionary models

    Deng Wang🇨🇳 · Xin-He Meng🇨🇳

    In this paper, we have proposed a plotting method based on the " natural plotting rule " (NPR) which can be used to distinguish different cosmological scenarios more efficiently and obtain more useful information. By using the NPR, we have avoided the blindness to use different diagnostics when discovering that some scenarios can be hardly differentiated from each other, and develop a logical line to adopt different diagnostics. As a concrete instance, we take this method based on the NPR to distinguish several Cardassian scenarios from the base cosmology scenario, and one from the other. We place constraints on three Cardassian cosmological scenarios and their flat versions by utilizing the Type Ia supernovae (SNe Ia), baryonic acoustic oscillations (BAO), cosmic microwave background (CMB) radiation, observational Hubble parameter (OHD) data-sets as well as the single data point from the newest event GW150914, and discover that our results are more stringent than previous results for constraining the cosmological parameters of the Cardassian scenarios. We find that the flat original Cardassian (FOC) and original Cardassian (OC) scenarios can only be distinguished in the plane of $\{{\Omega }_m,S_3^{(1)}\}$ at the present epoch, however, if applying the NPR to plot hierarchically for these Cardassian scenarios in the plane of $\{S_3^{(1)},S_4^{(1)}\}$, we can obtain more detailed information and distinguish the two scenarios better than before. More importantly, from the planes of $\{S_4,S_4^{(2)}\}$, $\{S_5^{(1)},S_5^{(2)}\}$, $\{S_3^{(2)},S_4^{(2)}\}$, $\{{\Omega }_m,S_3^{(1)}\}$,$\{z,\omega \}$ $\{ϵ(z),S_3^{(1)}\}$ and $\{z,Om\}$, we dsicover that the flat modified polytropic Cardassian (FMPC) scenario can be directly removed from the possible candidates of dark energy phenomenon, since its evolutional behavior deviates from the base cosmology scenario too much.

    Exploring Dense and Cold QCD in Magnetic Fields

    E. J. Ferrer🇺🇸 · V. de la Incera🇺🇸

    Strong magnetic fields are commonly generated in off-central relativistic heavy-ion collisions in the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab and in the Large Hadron Collider at CERN and have been used to probe the topological configurations of the QCD vacua. A strong magnetic field can affect the character and location of the QCD critical point, influence the QCD phases, and lead to anomalous transport of charge. To take advantage of the magnetic field as a probe of QCD at higher baryon densities, we are going to need experiments capable to scan the lower energy region. In this context, the nuclotron-based ion collider facility (NICA) at JINR offers a unique opportunity to explore such a region and complement alternative programs at RHIC and other facilities. In this paper we discuss some relevant problems of the interplay between QCD and magnetic fields and the important role the experiments at NICA can play in tackling them.

These include results for threshold ${\pi }^0$ production, deformation of $\Delta (1232)$, and the extracted properties of higher resonances below 2 GeV. The excellent agreement of DMT model's predictions with threshold ${\pi }^0$ production data, including the recent precision measurements from MAMI establishes results of DMT model as a benchmark for experimentalists and theorists in dealing with threshold pion production.

    Dilaton Stabilization in Three-generation Heterotic String Model

    Florian Beye🇯🇵 · Tatsuo Kobayashi🇯🇵 · Shogo Kuwakino🇹🇼

    We study dilaton stabilization in heterotic string models. By utilizing the asymmetric orbifold construction, we construct an explicit three-generation model whose matter content in the visible sector is the supersymmetric standard model with additional vectorlike matter. This model does not contain any geometric moduli fields except the dilaton field. Model building at a symmetry enhancement point in moduli space enlarges the rank of the hidden gauge group. By analyzing multiple hidden gauge sectors, the dilaton field is stabilized by the racetrack mechanism. We also discuss a supersymmetry breaking scenario and F-term uplifting.

    Quark-Jet model for transverse momentum dependent fragmentation functions

    W. Bentz🇯🇵 · A. Kotzinian🇦🇲 · H. H. Matevosyan🇦🇺 · Y. Ninomiya🇯🇵 · A. W. Thomas🇦🇺 · K. Yazaki🇯🇵

    In order to describe the hadronization of polarized quarks, we discuss an extension of the quark-jet model to transverse momentum dependent fragmentation functions. The description is based on a product ansatz, where each factor in the product represents one of the transverse momentum dependent splitting functions, which can be calculated by using effective quark theories. The resulting integral equations and sum rules are discussed in detail for the case of inclusive pion production. In particular, we demonstrate that the 3-dimensional momentum sum rules are satisfied naturally in this transverse momentum dependent quark-jet model. Our results are well suited for numerical calculations in effective quark theories, and can be implemented in Monte-Carlo simulations of polarized quark hadronization processes.

    Inclusive electron scattering within the SuSAv2-MEC approach

    G.D. Megias🇪🇸 · J.E. Amaro🇪🇸 · M.B. Barbaro🇮🇹 · J.A. Caballero🇪🇸 · T.W. Donnelly🇺🇸

    We present our recent progress on the relativistic modeling of electron-nucleus reactions and compare our predictions with inclusive ${}^{12}$C ($e,e^{\prime }$) experimental data in a wide kinematical region. The model, originally based on the superscaling phenomenon shown by electron-nucleus scattering data, has recently been improved through the inclusion of Relativistic Mean Field theory effects that take into account the enhancement of the transverse scaling function compared with its longitudinal counterpart. We also discuss the impact of meson-exchange currents (MEC) through the analysis of two-particle two-hole longitudinal and transverse contributions to electromagnetic response functions evaluated within the framework of the relativistic Fermi gas. The formalism is also extended to include the complete inelastic spectrum -- resonant, non-resonant and deep inelastic scattering (DIS). The results show quite good agreement with data over the whole range of energy transfer, including the dip region between the quasielastic peak and the $\Delta$ resonance.
