   Search for the glueball content of hadrons in gamma p interactions at GlueX

   Thomas Gutsche🇩🇪 · Serguei Kuleshov🇨🇱 · Valery E. Lyubovitskij🇩🇪 · Igor T. Obukhovsky🇷🇺

   We suggest a theoretical framework for the description of double photon and proton-antiproton photoproduction off the proton gamma + p -> 2 gamma + p and gamma + p -> antip + p + p which takes into account the contribution of the scalar mesons f0(1370), f0(1500) and f0(1710). These scalars are considered as mixed states of a glueball and nonstrange and strange quarkonia. Our framework is based on the use of effective hadronic Lagrangians that phenomenologically take into account two-gluon exchange effects governing the gamma + p -> 2 gamma + p and gamma + p -> antip + p + p processes. Present results can be used to guide the possible search for these reactions by the GlueX Collaboration at JLab.

   Enhanced Rates for Diphoton Resonances in the MSSM

   Abdelhak Djouadi🇫🇷 · Apostolos Pilaftsis🇬🇧

   We propose a simple mechanism for copiously producing heavy Higgs bosons with enhanced decay rates to two photons at the LHC, within the context of the Minimal Supersymmetric extension of the Standard Model (MSSM). In the CP-conserving limit of the theory, such a diphoton resonance may be identified with the heavier CP-even $H$ boson, whose gluon-fusion production and decay into two photons are enhanced by loops of the lightest supersymmetric partner of the top quark ${\tilde{t}}_1$ when its mass $m_{{\tilde{t}}_1}$ happens to be near the ${\tilde{t}}_1^{\ast }{\tilde{t}}_1$ threshold, i.e.~for $m_{{\tilde{t}}_1}\simeq \frac{1}{2}{M}_H$. The scenario requires a relatively low supersymmetry-breaking scale $M_S\stackrel{<}{{}_{\sim }}1$ TeV, but large values of the higgsino mass parameter, $\mu \stackrel{>}{{}_{\sim }}1$ TeV, that lead to a strong $H{\tilde{t}}_1^{\ast }{\tilde{t}}_1$ coupling. Such parameters can accommodate the observed mass and standard-like couplings of the 125 GeV $h$ boson in the MSSM, while satisfying all other constraints from the LHC and dark matter searches. Additional enhancement to the diphoton rate could be provided by Coulombic QCD corrections and, to a lesser extent, by resonant contributions due to ${\tilde{t}}_1^{\ast }{\tilde{t}}_1$ bound states. To discuss the characteristic features of such a scenario, we consider as an illustrative example the case of a diphoton resonance with a mass of approximately 750 GeV, for which an excess was observed in the early LHC 13 TeV data and which later turned out to be simply a statistical fluctuation.

   RECOLA: REcursive Computation of One-Loop Amplitudes

   Stefano Actis🇧🇪 · Ansgar Denner🇩🇪 · Lars Hofer🇪🇸 · Jean-Nicolas Lang🇩🇪 · Andreas Scharf🇩🇪 · Sandro Uccirati🇮🇹

   We present the Fortran95 program Recola for the perturbative computation of next-to-leading-order transition amplitudes in the Standard Model of particle physics. The code provides numerical results in the 't Hooft-Feynman gauge. It uses the complex-mass scheme and allows for a consistent isolation of resonant contributions. Dimensional regularization is employed for ultraviolet and infrared singularities, with the alternative possibility of treating collinear and soft singularities in mass regularization. Recola supports various renormalization schemes for the electromagnetic and a dynamical Nf-flavour scheme for the strong coupling constant. The calculation of next-to-leading-order squared amplitudes, summed over spin and colour, is supported as well as the computation of colour- and spin-correlated leading-order squared amplitudes needed in the dipole subtraction formalism.

   Falsifying Baryogenesis with Neutrinoless Double Beta Decay

   Lukas Graf🇬🇧

   We discuss the relation between lepton number violation at high and low energies, particularly, the constraints on baryogenesis models, which would be implied by an observation of neutrinoless double beta decay. The primordial baryon asymmetry can be washed out by effective lepton number violating operators triggering neutrinoless double beta decay in combination with sphaleron processes. A generic conclusion is that popular models of baryogenesis are excluded if a non-standard mechanism of neutrinoless double beta decay, i.e., other than the standard light neutrino exchange, is observed. Apart from the effective field approach, we also outline the possible extension of our arguments to a general UV-completed model.

   Distinguishing Dirac/Majorana Sterile Neutrinos at the LHC

   Claudio O. Dib🇨🇱 · C. S. Kim🇰🇷 · Kechen Wang🇨🇳 · Jue Zhang🇨🇳

   We study the purely leptonic decays of $W^{\pm }\to e^{\pm }{e}^{\pm }{\mu }^{\mp }\nu$ and ${\mu }^{\pm }{\mu }^{\pm }{e}^{\mp }\nu$ produced at the LHC, induced by sterile neutrinos with mass $m_N$ below $M_W$ in the intermediate state. Since the final state neutrino escapes detection, one cannot tell whether this process violates lepton number, what would indicate a Majorana character for the intermediate sterile neutrino. Our study shows that when the sterile neutrino mixings with electrons and muons are different enough, one can still discriminate between the Dirac and Majorana character of this intermediate neutrino by simply counting and comparing the above decay rates. After performing collider simulations and statistical analysis, we find that at the $14\text{TeV}$ LHC with an integrated luminosity of $3000{\text{fb}}^{-1}$, for two benchmark scenarios $m_N$ = 20 GeV and 50 GeV, at least a $3\sigma$ level of exclusion on the Dirac case can be achieved for disparities as mild as e.g. $|U_{Ne}{|}^2<0.7|U_{N\mu }{|}^2$ or $|U_{N\mu }{|}^2<0.7|U_{Ne}{|}^2$, provided that $|U_{Ne}{|}^2$, $|U_{N\mu }{|}^2$ are both above $\sim 2\times 10^{-6}$.

   Radiative Type III Seesaw Model and its collider phenomenology

   Federico von der Pahlen🇨🇴 · Guillermo Palacio🇨🇴 · Diego Restrepo🇨🇴 · Oscar Zapata🇨🇴

   We analyze the present bounds of a scotogenic model, the Radiative Type III Seesaw (RSIII), in which an additional scalar doublet and at least two fermion triplets of $SU(2{)}_L$ are added to the Standard Model (SM). In the RSIII the new physics (NP) sector is odd under an exact global $Z_2$ symmetry. This symmetry guaranties that the lightest NP neutral particle is stable, providing a natural dark matter (DM) candidate, and leads to naturally suppressed neutrino masses generated by a one-loop realization of an effective Weinberg operator. We focus on the region with the highest sensitivity in present and future LHC searches, with light scalar DM and at least one NP fermion triplet at the sub-TeV scale. This region allows for significant production cross-sections of NP fermion pairs at the LHC. We reinterpret a set of searches for supersymmetric particles at the LHC obtained using the package CheckMATE, to set limits on our model as a function of the masses of the NP particles and their Yukawa interactions. The most sensitive search channel is found to be dileptons plus missing transverse energy. In order to target the case of tau enhanced decays and the case of compressed spectra we reinterpret the recent slepton and chargino search bounds by ATLAS. For a lightest NP fermion triplet with a maximal branching ratio to either electrons or muons we exclude NP fermion masses of up to 650 GeV, while this bound is reduced to approximately 400 GeV in the tau-philic case. Allowing for a general flavor structure we set limits on the Yukawa couplings, which are directly related to the neutrino flavor structure.

   Heavy-flavored tetraquark states with the $QQ\bar{Q}\bar{Q}$ configuration

   Jing Wu🇨🇳 · Yan-Rui Liu🇨🇳 · Kan Chen🇨🇳 · Xiang Liu🇨🇳 · Shi-Lin Zhu🇨🇳

   In the framework of the color-magnetic interaction, we systematically investigate the mass spectrum of the tetraquark states composed of four heavy quarks with the $QQ\bar{Q}\bar{Q}$ configuration in this work. We also show their strong decay patterns. Stable or narrow states in the $bb\bar{b}\bar{c}$ and $bc\bar{b}\bar{c}$ systems are found to be possible. We hope the studies shall be helpful to the experimental search for heavy-full exotic tetraquark states.

   Transverse Momentum Dependent Parton Distributions with self-similarity at small $x$ and models of proton structure function

   D.K. Choudhury🇮🇳 · Baishali Saikia🇮🇳

   In this paper we make re-analysis of a self-similarity based model of the proton structure function at small $x$ pursued in recent years. The additional assumption is that it should be singularity free in the entire kinematic range $0\le \text{x}\le 1$. Our analysis indicates that the singularity free version of the model is valid in a more restrictive range of $Q^2$. We then analyse the defining Transverse Momentum Dependent Parton Distributions (TMD) occurred in the models and show that the proper generalizations and initial conditions on them not only remove the undesired singularity but also results in a QCD compatible structure function with logarithmic growth in $Q^2$. The phenomenological range of validity is then found to be much larger than the earlier versions. We also extrapolate the models to large $x$ in a parameter free way.

    Classically conformal U(1)' extended standard model, electroweak vacuum stability, and LHC Run-2 bounds

    Arindam Das🇺🇸 · Satsuki Oda🇯🇵 · Nobuchika Okada🇺🇸 · Dai-suke Takahashi🇯🇵

    We consider the minimal U(1)' extension of the standard model (SM) with the classically conformal invariance, where an anomaly-free U(1)' gauge symmetry is introduced along with three generations of right-handed neutrinos and a U(1)' Higgs field. Since the classically conformal symmetry forbids all dimensional parameters in the model, the U(1)' gauge symmetry is broken by the Coleman-Weinberg mechanism, generating the mass terms of the U(1)' gauge boson ($Z$' boson) and the right-handed neutrinos. Through a mixing quartic coupling between the U(1)' Higgs field and the SM Higgs doublet field, the radiative U(1)' gauge symmetry breaking also triggers the breaking of the electroweak symmetry. In this model context, we first investigate the electroweak vacuum instability problem in the SM. Employing the renormalization group equations at the two-loop level and the central values for the world average masses of the top quark ($m_t=173.34$ GeV) and the Higgs boson ($m_h=125.09$ GeV), we perform parameter scans to identify the parameter region for resolving the electroweak vacuum instability problem. Next we interpret the recent ATLAS and CMS search limits at the LHC Run-2 for the sequential $Z$' boson to constrain the parameter region in our model. Combining the constraints from the electroweak vacuum stability and the LHC Run-2 results, we find a bound on the $Z$' boson mass as $m_{Z^{\prime }}\gtrsim 3.5$ TeV. We also calculate self-energy corrections to the SM Higgs doublet field through the heavy states, the right-handed neutrinos and the $Z$' boson, and find the naturalness bound as $m_{Z^{\prime }}\lesssim 7$ TeV, in order to reproduce the right electroweak scale for the fine-tuning level better than 10\%. The resultant mass range of $3.5$ TeV $\lesssim m_{Z^{\prime }}\lesssim 7$ TeV will be explored at the LHC Run-2 in the near future.

    Topological Structure of the Vacuum, Cosmological Constant and Dark Energy

    B.G. Sidharth🇮🇳 · A. Das🇮🇳 · C.R. Das🇷🇺 · L.V. Laperashvili🇷🇺 · H.B. Nielsen🇩🇰

    In this review we present a theory of cosmological constant and Dark Energy (DE), based on the topological structure of the vacuum. The Multiple Point Principle (MPP) is reviewed. It demonstrates the existence of the two vacua into the SM. The Froggatt-Nielsen's prediction of the top-quark and Higgs masses is given in the assumption that there exist two degenerate vacua in the SM. This prediction was improved by the next order calculations. We also considered B.G. Sidharth's theory of cosmological constant based on the non-commutative geometry of the Planck scale space-time, what gives an extremely small DE density providing the accelerating expansion of the Universe. Theory of two degenerate vacua - the Planck scale phase and Electroweak (EW) phase - also is reviewed, topological defects in these vacua are investigated, also the Compton wavelength phase suggested by B.G. Sidharth was discussed. A general theory of the phase transition and the problem of the vacuum stability in the SM is reviewed. Assuming that the recently discovered at the LHC new resonance with mass $m_S\simeq 750$ GeV is a new scalar $S$ bound state $6t+6\bar{t}$, earlier predicted by C.D. Froggatt, H.B. Nielsen and L.V. Laperashvili, we try to provide the vacuum stability in the SM and exact accuracy of the MPP.

    Searches for top-Higgs FCNC couplings via the Whj signal with $h\to \gamma \gamma$ at the LHC

    Yao-Bei Liu🇨🇳 · Zhen-Jun Xiao🇨🇳

    In this paper, we investigated the process $pp\to W^{-}hj$ induced by the top-Higgs flavor changing neutral current (FCNC) couplings at the LHC. We found that the cross section of $pp\to W^{-}hj$ mainly comes from the resonant process $pp\to W^{-}t\to W^{-}hq$ due to the anomalous $tqH$ couplings (where $q$ denotes up and charm quarks). We further studied the observability of the top-Higgs FCNC couplings through the process $pp\to W^{-}(\to {\ell }^{-}{\bar{\nu }}_{\ell })h(\to \gamma \gamma )j$ and found that the branching ratios $Br(t\to qh)$ can be probed to $0.16\%$ at $3\sigma$ level at 14 TeV LHC with an integrated luminosity of 3000 fb${}^{-1}$.

    Hunting for Dark Particles with Gravitational Waves

    Gian F. Giudice🇨🇭 · Matthew McCullough🇨🇭 · Alfredo Urbano🇨🇭

    The LIGO observation of gravitational waves from a binary black hole merger has begun a new era in fundamental physics. If new dark sector particles, be they bosons or fermions, can coalesce into exotic compact objects (ECOs) of astronomical size, then the first evidence for such objects, and their underlying microphysical description, may arise in gravitational wave observations. In this work we study how the macroscopic properties of ECOs are related to their microscopic properties, such as dark particle mass and couplings. We then demonstrate the smoking gun exotic signatures that would provide observational evidence for ECOs, and hence new particles, in terrestrial gravitational wave observatories. Finally, we discuss how gravitational waves can test a core concept in general relativity: Hawking's area theorem.

    Neutrino masses and superheavy dark matter in the 3-3-1-1 model

    D. T. Huong🇻🇳 · P. V. Dong🇻🇳

    In this work, we interpret the 3-3-1-1 model when the B-L and 3-3-1 breaking scales behave simultaneously as the inflation scale. This setup not only realizes the previously-achieved consequences of inflation and leptogenesis, but also provides new insights in superheavy dark matter and neutrino masses. We argue that the 3-3-1-1 model can incorporate a scalar sextet, which induces both small masses for the neutrinos via a combined type I and II seesaw and large masses for the new neutral fermions. Additionally, all the new particles have the large masses in the inflation scale. The lightest particle among the W-particles that have abnormal (i.e., wrong) B-L number in comparison to those of the standard model particles may be a superheavy dark matter as it is stabilized by the W-parity. The dark matter candidate may be a Majorana fermion, a neutral scalar, or a neutral gauge boson, which was properly created in the early universe due to the gravitational effects on the vacuum or the thermal production after cosmic inflation.

    Direct Bethe-Salpeter solutions in Minkowski space

    J. Carbonell🇫🇷 · V.A. Karmanov🇷🇺

    We review a method to directly solve the Bethe-Salpeter equation in Minkowski space, both for bound and scattering states. It is based on a proper treatment of the many singularities which appear in the kernel and propagators. The off-mass shell scattering amplitude for spinless particles interacting by a one boson exchange was computed for the first time. Using our Minkowski space solutions for the initial (bound) and final (scattering) states, we calculate elastic and transition (bound to scattering state) electromagnetic form factors. The conservation of the transition electromagnetic current J.q=0, verified numerically, confirms the validity of our solutions.

    A minimal model of TeV scale WIMPy leptogenesis

    Arnab Dasgupta🇮🇳 · Chandan Hati🇮🇳 · Sudhanwa Patra🇮🇳 · Utpal Sarkar🇮🇳

    We present a minimal framework of $U(1{)}_{B-L}$ gauge extension of the Standard Model explaining dark matter abundance and matter-antimatter asymmetry simultaneously through an attractive mechanism of TeV scale WIMPy leptogenesis, testable at the current and next generation of colliders. This framework can also explain small neutrino masses via a radiative mechanism. One of the key predictions of this model is an enhanced rate for lepton flavor violating decay $\mu \to e\gamma$ within the sensitivity reach of next generation experiments.

    Magnetic moments of the hidden-charm pentaquark states

    Guang-Juan Wang🇨🇳 · Rui Chen🇨🇳 · Li Ma🇨🇳 · Xiang Liu🇨🇳 · Shi-Lin Zhu🇨🇳

    The magnetic moment of a baryon state is an equally important dynamical observable as its mass, which encodes crucial information of its underlying structure. According to the different color-flavor structure, we have calculated the magnetic moments of the hidden-charm pentaquark states with $J^P={\frac{1}{2}}^{\pm }$, ${\frac{3}{2}}^{\pm }$, ${\frac{5}{2}}^{\pm }$ and ${\frac{7}{2}}^{+}$ in the molecular model, the diquark-triquark model and the diquark-diquark-antiquark model respectively. Although a good description for the pentaquark mass spectrum and decay patterns has been obtained in all the three models, different color-flavor structures lead to different magnetic moments, which can be used to pin down their inner structures and distinguish various models.

    Parton Shower Uncertainties with Herwig 7: Benchmarks at Leading Order

    Johannes Bellm🇬🇧 · Graeme Nail🇬🇧 · Simon Plätzer🇬🇧 · Peter Schichtel🇬🇧 · Andrzej Siódmok🇨🇭

    We perform a detailed study of the sources of perturbative uncertainty in parton shower predictions within the Herwig 7 event generator. We benchmark two rather different parton shower algorithms, based on angular-ordered and dipole-type evolution, against each other. We deliberately choose leading order plus parton shower as the benchmark setting to identify a controllable set of uncertainties. This will enable us to reliably assess improvements by higher-order contributions in a follow-up work.

    Constraints on Axion-Like Particles from X-ray Observations of NGC1275

    Marcus Berg🇸🇪 · Joseph P. Conlon🇬🇧 · Francesca Day🇬🇧 · Nicholas Jennings🇬🇧 · Sven Krippendorf🇬🇧 · Andrew J. Powell🇬🇧 · Markus Rummel🇬🇧

    Axion-like particles (ALPs) can induce localised oscillatory modulations in the spectra of photon sources passing through astrophysical magnetic fields. Ultra-deep Chandra observations of the Perseus cluster contain over $5\times 10^5$ counts from the AGN of the central cluster galaxy NGC1275, and represent a dataset of extraordinary quality for ALP searches. We use this dataset to search for X-ray spectral irregularities from the AGN. The absence of irregularities at the O(30%) level allows us to place leading constraints on the ALP-photon mixing parameter $g_{a\gamma \gamma }\lesssim 1.4-4.0\times 10^{-12}{\mathrm{GeV}}^{-1}$ for $m_a\lesssim 10^{-12}$ eV, depending on assumptions on the magnetic field realisation along the line of sight.

    A Wilsonian Energy-Momentum Tensor

    Oliver J. Rosten

    For local conformal field theories, it is shown how to construct an expression for the energy-momentum tensor in terms of a Wilsonian effective Lagrangian. Tracelessness implies a single, unintegrated equation which enforces both the Exact Renormalization Group equation and its partner encoding invariance under special conformal transformations.

    Laser Interferometers as Dark Matter Detectors

    Evan D. Hall · Thomas Callister Valery V. Frolov · Holger Müller · Maxim Pospelov · Rana X Adhikari

    While global cosmological and local galactic abundance of dark matter is well established, its identity, physical size and composition remain a mystery. In this paper, we analyze an important question of dark matter detectability through its gravitational interaction, using current and next generation gravitational-wave observatories to look for macroscopic (kilogram-scale or larger) objects. Keeping the size of the dark matter objects to be smaller than the physical dimensions of the detectors, and keeping their mass as free parameters, we derive the expected event rates. For favorable choice of mass, we find that dark matter interactions could be detected in space-based detectors such as LISA at a rate of one per ten years. We then assume the existence of an additional Yukawa force between dark matter and regular matter. By choosing the range of the force to be comparable to the size of the detectors, we derive the levels of sensitivity to such a new force, which exceeds the sensitivity of other probes in a wide range of parameters. For sufficiently large Yukawa coupling strength, the rate of dark matter events can then exceed 10 per year for both ground- and space-based detectors. Thus, gravitational-wave observatories can make an important contribution to a global effort of searching for non-gravitational interactions of dark matter.

    Quark Matter at High Density based on Extended Confined-isospin-density-dependent-mass Model

    A. I. Qauli🇮🇩 · A. Sulaksono🇮🇩

    We investigate the effect of the inclusion of relativistic Coulomb terms in a confined-isospin-density-dependent-mass (CIDDM) model of strange quark matter (SQM). We found that if we include Coulomb term in scalar density form, SQM equation of state (EOS) at high densities is stiffer but if we include Coulomb term in vector density form is softer than that of standard CIDDM model. We also investigate systematically the role of each term of the extended CIDDM model. Compared with what was reported in Ref.~\cite {ref:isospin}, we found the stiffness of SQM EOS is controlled by the interplay among the the oscillator harmonic, isospin asymmetry and Coulomb contributions depending on the parameter's range of these terms. We have found that the absolute stable condition of SQM and the mass of 2 $M_{\odot }$ pulsars can constrain the parameter of oscillator harmonic ${\kappa }_1$ $\approx 0.53$ in the case Coulomb term excluded. If the Coulomb term is included, for the models with their parameters are consistent with SQM absolute stability condition, the $2.0M_{\odot }$ constraint more prefer the maximum mass prediction of model with scalar Coulomb term than that of model with vector Coulomb term. On contrary, the high densities EOS predicted by model with vector Coulomb is more compatible with recent pQCD result \cite{ref:pressure} than that predicted by model with scalar Coulomb. Furthermore, we also observed the quark composition in a very high density region depends quite sensitively on the kind of Coulomb term used.

    Kaon-Nucleon systems and their interactions in the Skyrme model

    Takashi Ezoe🇯🇵 · Atsushi Hosaka🇯🇵

    We study kaon-nucleon systems in the Skyrme model in a method based on the bound state approach of Callan-Klebanov but with the kaon around the physical nucleon of the rotating hedgehog. This corresponds to the variation after projection, reversing the order of semiclassical quantization of $1/N_c$ expansion. The method, however, is considered to be suited to the study of weakly interacting kaon-nucleon systems including loosely $\bar{K}N$ bound states such as $\Lambda (1405)$. We have found a bound state with binding energy of order ten MeV, consistent with the observed state. We also discuss the $\bar{K}N$ interaction and find that it consists of an attraction in the middle range and a repulsion in the short range.
