   Resolving ambiguities in model-independent partial-wave analysis of three-body decay

   F. Krinner🇩🇪 · D. Greenwald🇩🇪 · D. Ryabchikov🇷🇺 · B. Grube🇩🇪 · S. Paul🇩🇪

   Partial wave analysis is an important tool for analyzing large data sets in hadronic decays of light and heavy mesons. It commonly relies on the isobar model, which assumes multihadron final states originate from successive two-body decays of well-known undisturbed intermediate states. Recently, analyses of heavy-meson decays and diffractively produced states have attempted to overcome the strong model dependences of the isobar model. These analyses have overlooked that model-independent, or freed-isobar, partial-wave analysis can break the orthogonality of partial waves and introduce mathematical ambiguities into results. We show how these ambiguities arise and present general techniques for identifying their presence and for correcting for them. We demonstrate these techniques with specific examples in both heavy-meson decay and pion--proton scattering.

   First Monte Carlo global analysis of nucleon transversity with lattice QCD constraints

   Huey-Wen Lin🇺🇸 · W. Melnitchouk🇺🇸 · Alexei Prokudin🇺🇸 · N. Sato🇺🇸 · H. Shows III🇺🇸

   We report on the first global QCD analysis of the quark transversity distributions in the nucleon from semi-inclusive deep-inelastic scattering (SIDIS), using a new Monte Carlo method based on nested sampling and constraints on the isovector tensor charge $g_T$ from lattice QCD. A simultaneous fit to the available SIDIS Collins asymmetry data is compatible with $g_T$ values extracted from a comprehensive reanalysis of existing lattice simulations, in contrast to previous analyses which found significantly smaller $g_T$ values. The contributions to the nucleon tensor charge from $u$ and $d$ quarks are found to be $\delta u=0.3(2)$ and $\delta d=-0.7(2)$ at a scale $Q^2=2$ GeV${}^2$.

   Description of pp forward elastic scattering at 7 and 8 TeV

   A. K. Kohara🇧🇷 · E. Ferreira🇧🇷 · T. Kodama🇧🇷 · M. Rangel🇧🇷

   We analyse the recent LHC data at 7 and 8 TeV for pp elastic scattering with special attention for the structure of the real part, which is shown to be crucial to describe the differential cross section in the forward region. We determine accurately the position of the zero of the real amplitude, which corresponds to the zero of a theorem by A. Martin.

   Realistic simplified gaugino-higgsino models in the MSSM

   Benjamin Fuks🇫🇷 · Michael Klasen🇩🇪 · Saskia Schmiemann🇩🇪 · Marthijn Sunder🇩🇪

   We present simplified MSSM models for light neutralinos and charginos with realistic mass spectra and realistic gaugino-higgsino mixing, that can be used in experimental searches at the LHC. The formerly used naive approach of defining mass spectra and mixing matrix elements manually and independently of each other does not yield genuine MSSM benchmarks. We suggest the use of less simplified, but realistic MSSM models, whose mass spectra and mixing matrix elements are the result of a proper matrix diagonalisation. We propose a novel strategy targeting the design of such benchmark scenarios, accounting for user-defined constraints in terms of masses and particle mixing. We apply it to the higgsino case and implement a scan in the four relevant underlying parameters {{\mu}, tan\beta, M_1, M_2} for a given set of light neutralino and chargino masses. We define a measure for the quality of the obtained benchmarks, that also includes criteria to assess the higgsino content of the resulting charginos and neutralinos. We finally discuss the distribution of the resulting models in the MSSM parameter space as well as their implications for supersymmetric dark matter phenomenology.

   Search for $W^{\prime }$ signal in single top quark production at LHC

   Fei Huang🇨🇳 · Hong-Lei Li🇨🇳 · Shi-Yuan Li🇨🇳 · Zong-Guo Si🇨🇳 · Wei Su🇨🇳 · Zhong-Juan Yang🇨🇳

   The heavy charged gauge bosons were proposed in the theories beyond standard model. We explore the discovery potential for $W^{\prime }\to t\bar{b}$ with top quark semi-leptonic decay at the LHC. We concentrate on the new physics signal search with the deviation from the standard model prediction if the resonance peak of $W^{\prime }$ can not be observed directly. The events of signal with two jets plus one charged lepton and missing energy are simulated together with the dominant standard model backgrounds. In this paper, it is found that suitable cuts on the kinematic observables can effectively suppress the standard model backgrounds, so that it is possible to search for $W^{\prime }$ signal at the LHC with its mass less than 6.6 TeV.

   Theory overview of tree-level $B$ decays

   Fulvia De Fazio🇮🇹

   I describe the theoretical progress in the study of semileptonic tree-level B decays, and its interplay with recent experimental results. In particular, I focus on two anomalies: the ratios $R(D^{(\ast )})=\frac{\mathcal{B}(B\to D^{(\ast )}\tau {\bar{\nu }}_{\tau })}{\mathcal{B}(B\to D^{(\ast )}\ell {\bar{\nu }}_{\ell })}$ and the inclusive versus exclusive determination of $|V_{cb}|$. I review a few explanations proposed for such anomalies, and discuss tests to shed light on their origin.

   Left-handed and right-handed U(1) gauge symmetry

   Takaaki Nomura🇰🇷 · Hiroshi Okada🇹🇼

   We propose a model with the left-handed and right-handed continuous Abelian gauge symmetry; $U(1{)}_L\times U(1{)}_R$. Then three right-handed neutrinos are naturally required to achieve $U(1{)}_R$ anomaly cancellations, while several mirror fermions are also needed to do $U(1{)}_L$ anomaly cancellations. Then we formulate the model, and discuss its testability of the new gauge interactions at collider physics such as the large hadron collider (LHC) and the international linear collider (ILC). In particular, we can investigate chiral structure of the interactions by the analysis of forward-backward asymmetry based on polarized beam at the ILC.

   Large-$N_c$ operator analysis of hyperon-nucleon interactions in SU(3) chiral effective field theory

   Xuyang Liu🇨🇳 · Viroj Limkaisang🇹🇭 · Daris Samart🇹🇭 · Yupeng Yan🇹🇭

   We study octet-octet baryon ($J^P={\frac{1}{2}}^{+}$) contact interactions in SU(3) chiral effective field theory by using large-$N_c$ operator analysis. Applying the $1/N_c$ expansion of the Hartee Hamiltonian, we find 15 operators in the octet-octet baryon potential where 4 operators for leading order (LO) and 11 for and net-to-next-to-leading order (NNLO). The large-$N_c$ operator analysis of octet-octet baryon matrix elements reduces the number of free parameters from 15 to 6 at LO of the $1/N_c$ expansion. The application of large-$N_c$ sum rules to the Jülich model of hyperon-nucleon (YN) interactions at the LO of the chiral expansion reduces the model parameters to 3 from 5 at the LO of $1/N_c$ expansion. We find that the values of LECs fitted to YN scattering data in Ref. \cite{Li:2016paq} in the relativistic covariant ChEFT (EG) approach is more consistent with the predictions of large-$N_c$ than in the heavy baryon (HB) formalism approach.

   Color dipole predictions for the exclusive vector meson photoproduction in $pp/pPb/PbPb$ collisions at Run 2 LHC energies

   V. P. Goncalves🇧🇷 · M.V.T. Machado🇧🇷 · B. D. Moreira🇧🇷 · F. S. Navarra🇧🇷 · G. Sampaio dos Santos🇧🇷

   In this paper we present a comprehensive analysis of exclusive vector meson photoproduction in $pp$, $pPb$ and $PbPb$ collisions at Run 2 LHC energies using the Color Dipole formalism. The rapidity distributions and total cross sections for the $\rho$, $\varphi$, $J/\Psi$, $\Psi (2S)$ and ${\rm Y}$ production are estimated considering the more recent phenomenological models for the dipole - proton scattering amplitude, which are based on the Color Glass Condensate formalism and are able to describe the inclusive and exclusive $ep$ HERA data. Moreover, we also discuss the impact of the modelling of the vector meson wave functions on the predictions. The current theoretical uncertainty in the Color Dipole predictions is estimated and a comparison with the experimental results is performed.

    Exploring Non-Holomorphic Soft Terms in the Framework of Gauge Mediated Supersymmetry Breaking

    Utpal Chattopadhyay🇮🇳 · Debottam Das🇮🇳 · Samadrita Mukherjee🇮🇳

    It is known that in the absence of a gauge singlet field, a specific class of supersymmetry (SUSY) breaking non-holomorphic (NH) terms can be soft breaking in nature so that they may be considered along with the Minimal Supersymmetric Standard Model (MSSM) and beyond. There have been studies related to these terms in minimal supergravity based models. Consideration of an F-type SUSY breaking scenario in the hidden sector with two chiral superfields however showed Planck scale suppression of such terms. In an unbiased point of view for the sources of SUSY breaking, the NH terms in a phenomenological MSSM (pMSSM) type of analysis showed a possibility of a large SUSY contribution to muon $g-2$, a reasonable amount of corrections to the Higgs boson mass and a drastic reduction of the electroweak fine-tuning for a higgsino dominated ${\tilde{\chi }}_1^0$ in some regions of parameter space. We first investigate here the effects of the NH terms in a low scale SUSY breaking scenario. In our analysis with minimal gauge mediated supersymmetry breaking (mGMSB) we probe how far the results can be compared with the previous pMSSM plus NH terms based study. We particularly analyze the Higgs, stop and the electroweakino sectors focusing on a higgsino dominated ${\tilde{\chi }}_1^0$ and ${\tilde{\chi }}_1^{\pm }$, a feature typically different from what appears in mGMSB. The effect of a limited degree of RG evolutions and vanishing of the trilinear coupling terms at the messenger scale can be overcome by choosing a non-minimal GMSB scenario, such as one with a matter-messenger interaction.

    Searching for new light gauge bosons at $e^{+}{e}^{-}$ colliders

    I. Alikhanov🇷🇺 · E. A. Paschos🇩🇪

    Neutral gauge bosons beyond the Standard Model are becoming interesting as possible mediators to explain several experimental anomalies. They have small masses, below one GeV, and are referred to as dark photons, $U$, $A^{\prime }$ or $Z^{\prime }$ bosons. Electron--positron collision experiments at the B-factories provide the most straightforward way to probe bosons of this kind. In the present article we study production of the bosons at $e^{+}{e}^{-}$ colliders operating at GeV center-of-mass energies. We have studied two channels: $e^{+}{e}^{-}\to \gamma Z^{\prime }$ and $e^{+}{e}^{-}\to e^{+}{e}^{-}{Z}^{\prime }$. Analytic expressions for the cross sections and various observables such as the energy spectra of the produced bosons and the final electrons from the $Z^{\prime }$ decays are derived. We have also studied the transverse momentum distribution of the bosons and the spatial distribution of the $Z^{\prime }\to e^{+}{e}^{-}$ decay vertices. It is shown that these distributions provide distinct signatures of the bosons in $e^{+}{e}^{-}\to \gamma Z^{\prime }$. The reaction $e^{+}{e}^{-}\to e^{+}{e}^{-}{Z}^{\prime }$ becomes important at small $Z^{\prime }$ scattering angles where its contribution to the overall yield may be larger by orders of magnitude compared to $e^{+}{e}^{-}\to \gamma Z^{\prime }$. The standard processes $e^{+}{e}^{-}\to \gamma \gamma$ and $e^{+}{e}^{-}\to e^{+}{e}^{-}\gamma$ that lead to the same signal are considered. We include numerical predictions for the production rates at the energy $\sqrt{s}=10.5$ GeV. The case with a light scalar boson is also discussed. The calculations are performed in detail and can be useful for additional studies.

    Study of $2S$- and $1D$- excitations of observed charmed strange baryons

    Dan-Dan Ye🇨🇳 · Ze Zhao🇨🇳 · Ailin Zhang🇨🇳

    Strong decays of ${\Xi }_c$ baryons with radial or orbital excitations with positive parity have been studied in a ${}^3{P}_0$ model. As candidates of these $X{i}_c$, possible configurations and $J^P$ of ${\Xi }_c(2930)$, ${\Xi }_c(2980)$, ${\Xi }_c(3055)$, ${\Xi }_c(3080)$ and ${\Xi }_c(3123)$ have been assigned. There are $40$ kinds of configurations to describe these excited ${\Xi }_c$. In these assignments, ${\Xi }_c(2930)$ may be a $2S$-wave excited ${\tilde{\Xi }}_{c1}({\frac{1}{2}}^{+})$ or ${\tilde{\Xi }}_{c1}({\frac{3}{2}}^{+})$, or a $D$-wave excited ${\hat{\Xi }}_{c1}^{{}^{\prime }}({\frac{1}{2}}^{+})$, ${\check{\Xi }}_{c1}^0({\frac{1}{2}}^{+})$, ${\check{\Xi }}_{c1}^2({\frac{1}{2}}^{+})$, ${\hat{\Xi }}_{c1}^{{}^{\prime }}({\frac{3}{2}}^{+})$, ${\check{\Xi }}_{c1}^0({\frac{3}{2}}^{+})$ or ${\check{\Xi }}_{c1}^2({\frac{3}{2}}^{+})$. ${\Xi }_c(2980{)}^{+}$ may be a $2S$-wave excited ${\tilde{\Xi }}_{c1}({\frac{1}{2}}^{+})$ or ${\tilde{\Xi }}_{c0}^{{}^{\prime }}({\frac{1}{2}}^{+})$ with $J^P={\frac{1}{2}}^{+}$, or a $D$-wave excited ${\check{\Xi }}_{c0}^{{}^{\prime }0}({\frac{1}{2}}^{+})$ or ${\check{\Xi }}_{c1}^0({\frac{1}{2}}^{+})$ with $J^P={\frac{1}{2}}^{+}$. ${\Xi }_c(3055{)}^{+}$ may be a $2S$-wave excited ${\acute{\Xi }}_{c1}^{{}^{\prime }}({\frac{3}{2}}^{+})$ or ${\acute{\Xi }}_{c0}({\frac{1}{2}}^{+})$. It may be a $D$-wave excited ${\Xi }_{c1}^{{}^{\prime }}({\frac{3}{2}}^{+})$, ${\Xi }_{c2}^{{}^{\prime }}({\frac{5}{2}}^{+})$, ${\Xi }_{c2}^{}({\frac{3}{2}}^{+})$ or ${\Xi }_{c2}^{}({\frac{5}{2}}^{+})$. ${\Xi }_c(3080{)}^{+}$ is very possibly a $2S$-wave excited ${\acute{\Xi }}_{c0}({\frac{1}{2}}^{+})$, and seems not a $D$-wave excitation of ${\Xi }_c$. For the poor experimental information of ${\Xi }_c(3123)$, it is impossible to identify this state at present. It is found that the channel $\Lambda D$ vanishes in the strong decay of $P$-wave, $D$-wave and $2S$-wave excited ${\Xi }_c$ without $\rho$- mode excitation between the two light quarks ($n_{\rho }=L_{\rho }=0$). Some branching fraction ratios have been computed and can be employed to distinguish different configurations in forthcoming experiments.

    Effective Field Theory for Dark Matter Direct Detection up to Dimension Seven

    Joachim Brod🇩🇪 · Aaron Gootjes-Dreesbach🇩🇪 · Michele Tammaro🇺🇸 · Jure Zupan🇺🇸

    We present the full basis of effective operators relevant for dark matter direct detection, up to and including operators of mass dimension seven. We treat the cases where dark matter is either a Dirac fermion, a Majorana fermion, a complex scalar, or a real scalar, allowing for dark matter to furnish a general representation of the electroweak gauge group. We describe the algorithmic procedure used to obtain the minimal set of effective operators and provide the tree-level matching conditions onto the effective theory valid below the electroweak scale.

    Texture Zero Neutrino Models and Their Connection with Resonant Leptogenesis

    Avtandil Achelashvili🇬🇪 · Zurab Tavartkiladze🇬🇪

    Within the low scale resonant leptogenesis scenario, the cosmological CP asymmetry may arise by radiative corrections through the charged lepton Yukawa couplings. While in some cases, as one expects, decisive role is played by the ${\lambda }_{\tau }$ coupling, we show that in specific neutrino textures only by inclusion of the ${\lambda }_{\mu }$ the cosmological CP violation is generated at 1-loop level. With the purpose to relate the cosmological CP violation to the leptonic CP phase $\delta$, we consider an extension of MSSM with two right handed neutrinos (RHN), which are degenerate in mass at high scales. Together with this, we first consider two texture zero $3\times 2$ Dirac Yukawa matrices of neutrinos. These via see-saw generated neutrino mass matrices augmented by single $\Delta L=2$ dimension five ($\mathrm{d}=5$) operator give predictive neutrino sectors with calculable CP asymmetries. The latter is generated through ${\lambda }_{\mu ,\tau }$ coupling(s) at 1-loop level. Detailed analysis of the leptogenesis is performed. We also revise some one texture zero Dirac Yukawa matrices, considered earlier, and show that addition of a single $\Delta L=2$, $\mathrm{d}=5$ entry in the neutrino mass matrices, together with newly computed 1-loop corrections to the CP asymmetries, give nice accommodation of the neutrino sector and desirable amount of the baryon asymmetry via the resonant leptogenesis even for rather low RHN masses($\sim$few TeV -- $10^7$~GeV).

    Constraining Warm Inflation with CMB data

    Mar Bastero-Gil🇪🇸 · Sukannya Bhattacharya🇮🇳 · Koushik Dutta🇮🇳 · Mayukh Raj Gangopadhyay🇮🇳

    We confront the warm inflation observational predictions directly with the latest CMB data. We focus on a linear temperature (T) dissipative coefficient combined with the simplest model of inflation, a quartic chaotic potential. Although excluded in its standard cold inflation version, dissipation reduces the tensor-to-scalar ratio and brings the quartic chaotic model within the observable allowed range. We will use the CosmoMC package to derive constraints on the model parameters: the combination of coupling constants giving rise to dissipation, the effective number of relativistic degrees of freedom contributing to the thermal bath, and the quartic coupling in the inflaton potential. We do not assume a priori a power-law primordial spectrum, neither we fix the no. of e-folds at the horizon exit. The relation between the no. of e-folds and the comoving scale at horizon crossing is derived from the dynamics, depending on the parameters of the model, which allows us to obtain the $k$-dependent primordial power spectrum. We study the two possibilities considered in the literature for the spectrum, with the inflaton fluctuations having a thermal or a non-thermal origin, and discuss the ability of the data to constraint the model parameters.

    A lattice calculation of the hadronic vacuum polarization contribution to $(g-2{)}_{\mu }$

    We present results of calculations of the hadronic vacuum polarisation contribution to the muon anomalous magnetic moment. Specifically, we focus on controlling the infrared regime of the vacuum polarisation function. Our results are corrected for finite-size effects by combining the Gounaris-Sakurai parameterisation of the timelike pion form factor with the Lüscher formalism. The impact of quark-disconnected diagrams and the precision of the scale determination is discussed and included in our final result in two-flavour QCD, which carries an overall uncertainty of 6%. We present preliminary results computed on ensembles with $N_f=2+1$ dynamical flavours and discuss how the long-distance contribution can be accurately constrained by a dedicated spectrum calculation in the iso-vector channel.

    A minimal approach to the scattering of physical massless bosons

    Rutger H. Boels🇩🇪 · Hui Luo🇩🇪

    Tree and loop level scattering amplitudes which involve physical massless bosons are derived directly from physical constraints such as locality, symmetry and unitarity, bypassing path integral constructions. Amplitudes can be projected onto a minimal basis of kinematic factors through linear algebra, by employing four dimensional spinor helicity methods or at its most general using projection techniques. The linear algebra analysis is closely related to amplitude relations, especially the Bern-Carrasco-Johansson relations for gluon amplitudes and the Kawai-Lewellen-Tye relations between gluons and graviton amplitudes. Projection techniques are known to reduce the computation of loop amplitudes with spinning particles to scalar integrals. Unitarity, locality and integration-by-parts identities can then be used to fix complete tree and loop amplitudes efficiently. The loop amplitudes follow algorithmically from the trees. A range of proof-of-concept examples is presented. These include the planar four point two-loop amplitude in pure Yang-Mills theory as well as a range of one loop amplitudes with internal and external scalars, gluons and gravitons. Several interesting features of the results are highlighted, such as the vanishing of certain basis coefficients for gluon and graviton amplitudes. Effective field theories are naturally and efficiently included into the framework. The presented methods appear most powerful in non-supersymmetric theories in cases with relatively few legs, but with potentially many loops. For instance, iterated unitarity cuts of four point amplitudes for non-supersymmetric gauge and gravity theories can be computed by matrix multiplication, generalising the so-called rung-rule of maximally supersymmetric theories. The philosophy of the approach to kinematics also leads to a technique to control color quantum numbers of scattering amplitudes with matter.

    Comment on "Characterizing the population of pulsars in the Galactic bulge with the $\text{Fermi}$ Large Area Telescope" [arXiv:1705.00009v1]

    Richard Bartels🇳🇱 · Dan Hooper🇺🇸 · Tim Linden🇺🇸 · Siddharth Mishra-Sharma🇺🇸 · Nicholas L. Rodd🇺🇸 · Benjamin R. Safdi🇺🇸 · Tracy R. Slatyer🇺🇸

    The $\text{Fermi}$-LAT Collaboration recently presented a new catalog of gamma-ray sources located within the $40^{\circ }\times 40^{\circ }$ region around the Galactic Center~(Ajello et al. 2017) -- the Second Fermi Inner Galaxy (2FIG) catalog. Utilizing this catalog, they analyzed models for the spatial distribution and luminosity function of sources with a pulsar-like gamma-ray spectrum. Ajello et al. 2017 v1 also claimed to detect, in addition to a disk-like population of pulsar-like sources, an approximately 7$\sigma$ preference for an additional centrally concentrated population of pulsar-like sources, which they referred to as a "Galactic Bulge" population. Such a population would be of great interest, as it would support a pulsar interpretation of the gamma-ray excess that has long been observed in this region. In an effort to further explore the implications of this new source catalog, we attempted to reproduce the results presented by the $\text{Fermi}$-LAT Collaboration, but failed to do so. Mimicking as closely as possible the analysis techniques undertaken in Ajello et al. 2017, we instead find that our likelihood analysis favors a very different spatial distribution and luminosity function for these sources. Most notably, our results do not exhibit a strong preference for a "Galactic Bulge" population of pulsars. Furthermore, we find that masking the regions immediately surrounding each of the 2FIG pulsar candidates does $\text{not}$ significantly impact the spectrum or intensity of the Galactic Center gamma-ray excess. Although these results refute the claim of strong evidence for a centrally concentrated pulsar population presented in Ajello et al. 2017, they neither rule out nor provide support for the possibility that the Galactic Center excess is generated by a population of low-luminosity and currently largely unobserved pulsars.
