   Neutrino refraction by the cosmic neutrino background

   J.S. Diaz🇩🇪 · F.R. Klinkhamer🇩🇪

   We have determined the dispersion relation of a neutrino test particle propagating in the cosmic neutrino background. Describing the relic neutrinos and antineutrinos from the hot big bang as a dense medium, a matter potential or refractive index is obtained. The vacuum neutrino mixing angles are unchanged, but the energy of each mass state is modified. Using a matrix in the space of neutrino species, the induced potential is decomposed into a part which produces signatures in beta-decay experiments and another part which modifies neutrino oscillations. The low temperature of the relic neutrinos makes a direct detection extremely challenging. From a different point of view, the identified refractive effects of the cosmic neutrino background constitute an ultralow background for future experimental studies of nonvanishing Lorentz violation in the neutrino sector.

   Modeling of processes with anomalous interactions by means of auxiliary fields

   E. Boos🇷🇺 · V. Bunichev🇷🇺 · L. Dudko🇷🇺 · M. Perfilov🇷🇺

   The paper presents a method of modeling events with anomalous fermion-boson couplings by means of an auxiliary vector fields in addition to the SM gauge field. The method allows to simulate anomalous gauge couplings in different approaches, keeping only the linear order or higher order contributions of the anomalous couplings. The effectiveness of proposed method is demonstrated by modeling the single top quark production processes with anomalous Wtb couplings.

   Hyperon elastic electromagnetic form factors in the space-like momentum region

   Helios Sanchis-Alepuz🇩🇪 · Christian S. Fischer🇩🇪

   We present a calculation of the electric and magnetic form factors of ground-state octet and decuplet baryons including strange quarks. We work with a combination of Dyson-Schwinger equations for the quark propagator and covariant Bethe-Salpeter equations describing baryons as bound states of three (non-perturbative) quarks. Our form factors for the octet baryons are in good agreement with corresponding lattice data at finite $Q^2$; deviations in some isospin channels for the magnetic moments can be explained by missing meson cloud effects. At larger $Q^2$ our quark core calculation has predictive power for both, the octet and decuplet baryons.

   Towards a complete $\Delta (27)\times SO(10)$ SUSY GUT

   Fredrik Björkeroth🇬🇧 · Francisco J. de Anda🇲🇽 · Ivo de Medeiros Varzielas🇬🇧 · Stephen F. King🇬🇧

   We propose a renormalisable model based on $\Delta (27)$ family symmetry with an $SO(10)$ grand unified theory (GUT) leading to a novel form of spontaneous geometrical CP violation. The symmetries, including $\Delta (27)$ and ${\mathbb{Z}}_9\times {\mathbb{Z}}_{12}\times {\mathbb{Z}}_4^R$, are broken close to the GUT breaking scale to yield the minimal supersymmetric standard model (MSSM) with the standard R-parity. $SO(10)$ is broken via $SU(5)$ with doublet-triplet splitting achieved by a version of the Dimopoulos-Wilczek (missing VEV) mechanism. Low-scale Yukawa structure is dictated by the coupling of matter to $\Delta (27)$ antitriplets $\bar{\varphi }$ whose VEVs are aligned in the CSD3 directions by the superpotential. Light physical Majorana neutrinos masses emerge from a specific implementation of the seesaw mechanism within $SO(10)$. The model predicts a normal neutrino mass hierarchy with the best-fit lightest neutrino mass $m_1=0.13$ meV and the PMNS mixing parameters ${\theta }_{13}^l\approx 8.35^{\circ }$, ${\theta }_{12}^l\approx 34^{\circ }$, ${\theta }_{23}^l\approx 43^{\circ }$ and an oscillation phase ${\delta }^l\approx -90^{\circ }$.

   Calculating Soft Radiation at One Loop

   Tomas Kasemets🇳🇱 · Wouter J. Waalewijn🇳🇱 · Lisa Zeune🇳🇱

   We present an efficient way to calculate the effect of soft QCD radiation at one loop, which is needed for predictions at next-to-next-to-leading logarithmic accuracy. We use rapidity coordinates and isolate the divergences in the integrand. By performing manipulations with cumulative variables, we avoid complications from plus distributions. We address rapidity divergences, divergences with an azimuthal dependence, complicated jet boundaries and multi-differential measurements. The process and measurements can be easily adjusted, as we demonstrate by reproducing many existing soft functions. The results for a general LHC process with multiple Wilson lines are obtained by treating Wilson lines that are not back-to-back using a boost. We also obtain, for the first time, the N-jettiness soft function for generic jet angularities, and the collinear-soft function for the measurement of two angularities.

   Non-Abelian family symmetries as portals to dark matter

   Ivo de Medeiros Varzielas🇬🇧 · Oliver Fischer🇨🇭

   Non-Abelian family symmetries offer a very promising explanation for the flavour structure in the Standard Model and its extensions. We explore the possibility that dark matter consists in fermions that transform under a family symmetry, such that the visible and dark sector are linked by the familons - Standard Model gauge singlet scalars, responsible for spontaneously breaking the family symmetry. We study three representative models with non-Abelian family symmetries that have been shown capable to explain the masses and mixing of the Standard Model fermions. One of our central results is the possibility to have dark matter fermions and at least one familon with masses on and even below the experimentally accessible TeV scale. In particular we discuss the characteristic signatures in collider experiments from light familon Fields with a non-Abelian family symmetry, and we show that run I of the LHC is already testing this class of models.

   The perturbative QCD factorization of $\rho {\gamma }^{\star }\to \rho$

   Ya-lan Zhang🇨🇳 · Shan Cheng🇩🇪 · Jun Hua🇨🇳 · Zhen-jun Xiao🇨🇳

   In this paper we firstly demonstrate step by step that the factorization hypothesis is valid at the next-to-leading order (NLO) for the exclusive process $\rho {\gamma }^{\star }\to \rho$ by employing the collinear factorization approach, and then extend this proof to the case of the $k_T$ factorization by taking into account the transversal momentum of the light external quark (anti-quark) lines in the $\rho$ meson. At the NLO level, we then show that the soft divergences from different sub-diagrams will be canceled each other in the quark level, while the remaining collinear divergences can be absorbed into the NLO meson wave functions. The full NLO amplitudes can therefore be factorized as the convolution of the NLO wave functions ${\Phi }_{\rho }^{(1)}$ and the infrared-finite leading order (LO) hard kernels $G_{X,IJ,kl}^0$ in the $k_T$ factorization. We also write down the polarized NLO $\rho$ meson wave functions in the form of nonlocal hadron matrix elements with the gauge factor integral path deviating from the light cone. These NLO $\rho$ meson wave functions can be used to calculate the NLO hard corrections to some relevant exclusive processes, such as $B\to \rho$ transition.

   Muon g-2 through a flavor structure on soft SUSY terms

   F.V. Flores-Baez (UANL)🇲🇽 · M. Gomez-Bock (UDLAP)🇲🇽 · M. Mondragon (UNAM)🇲🇽

   In this work we analyze the possibility to explain the muon anomalous magnetic moment discrepancy within theory and experiment through lepton flavor violation processes. We propose a flavor extended MSSM by considering a hierarchical family structure for the trilinear scalar Soft-Supersymmetric terms of the Lagranagian, present at the SUSY breaking scale. We obtain analytical results for the rotation mass matrix, with the consequence of having non-universal slepton masses and the possibility of leptonic flavour mixing. The one-loop supersymmetric contributions to the leptonic flavour violating process $\tau \to \mu \gamma$ are calculated in the physical basis, with slepton flavour mixed states, instead of using the well known Mass Insertion Method. We present the regions in parameter space where the muon g-2 problem is either entirely solved or partially reduced through the contribution of these flavor violating processes.

   We demonstrate the usefulness of flavour neutrino masses expressed in terms of $M_{ee},M_{e\mu }$ and $M_{e\tau }$. The analytical expressions for the flavour neutrino masses, mass eigenstates and physical CP-violating Majorana phases for texture two zeros are obtained exactly.

    Real and virtual $N\bar{N}$ pair production near the threshold

    V. F. Dmitriev🇷🇺 · A. I. Milstein🇷🇺 · S. G. Salnikov🇷🇺

    Nucleon-antinucleon optical potential, which explains the experimental data for the processes $e^{+}{e}^{-}\to p\bar{p}$ and $e^{+}{e}^{-}\to \text{mbox}pions$ near the threshold of $p\bar{p}$ pair production, is suggested. To obtain this potential we have used the available experimental data for $p\bar{p}$ scattering, $p\bar{p}$ pair production in $e^{+}{e}^{-}$ annihilation, and the ratio of electromagnetic form factors of a proton in the timelike region. It turns out that final-state interaction via the optical potential allows one to reproduce the available experimental data with good accuracy. Our results for the cross sections of $e^{+}{e}^{-}\to 6\pi$ process near the threshold of $p\bar{p}$ pair production are in agreement with the recent experiments.

    Renormalization Scheme Dependence in b->u Semileptonic Decays

    D.G.C. McKeon🇨🇦

    After reviewing how the renormalization group equation can be used to sum logarithmic corrections to the decay rate for the semi-leptonic process b->u when using minimal subtraction, we consider renormalization scheme dependence for this calculation when employing this renor- malization scheme. In this calculation, an ambiguity resides in the running strong coupling and in the running b quark mass. The ambiguity usually associated with the renormalization mass scale mu is shown to cancel. It is demonstrated how in one renormalization scheme, there are only leading-log contributions to this decay rate. Another choice of renormalization scheme results in the decay rate being expressed in terms of the two-loop contribution to the beta-function associated with the strong coupling and the one-loop contribution to the anomalous mass dimension as well as a set of renormalization scheme invariant parameters.

    Pion-induced production of the $Z_c(3900)$ off a nuclear target

    Yin Huang🇨🇳 · Jun He🇨🇳 · Xiang Liu🇨🇳 · Hong Fei Zhang🇨🇳 · Ju Jun Xie🇨🇳 · Xu Rong Chen🇨🇳

    We investigate the possibility to study the charmoniumlike state $Z_c(3900)$ through the pion-induced production off a nuclear target. By using a high-energy pion beam, the $Z_c(3900)$ can be produced off a proton or nucleus though the Primakoff effect. The production amplitude is calculated in an effective Lagrangian approach combined with the vector dominance model. The total cross sections of the $p({\pi }^{-},Z_c^{-}(3900))$ and $p({\pi }^{-},Z_c^{-}(3900)\to J/\psi {\pi }^{-})$ reactions are calculated, and their order of magnitude is about 0.1 and 0.01nb, respectively, with an assumption of branch ratio 10\% for the $Z_c(3900)$ decay in $J/\psi \pi$ channel. If the proton target is replaced by a nuclear target, the production of the $Z_c(3900)$ enhances obviously. The predicted total cross sections for the $A({\pi }^{-},Z_c^{-}(3900))$ and $A({\pi }^{-},Z_c^{-}(3900)\to J/\psi {\pi }^{-})$ reactions with $A{=}^{12}$C or ${}^{208}$Pb are on the order of magnitude of 100 and 10 nb, respectively, which is about one thousand times larger than the cross sections off a proton target. Based on these the results, we suggest the experimental study of the $Z_c(3900)$ by using high-energy pion beams with a nuclear target at facilities such as COMPASS and J-PARC.

    Electron dressed mass in short laser pulses and its measurement

    F. Cajiao Vélez🇵🇱 · K. Krajewska🇵🇱 · J. Z. Kamiński🇵🇱

    The concept of the electron mass dressing by a powerful laser pulse is discussed. It is shown, by considering the coherent frequency combs generated out of the Compton radiation, how the electron dressed mass can be determined experimentally. This also opens a possibility to measure properties of extremely intense pulses for which the previously developed methods, working at moderate intensities, are not applicable. Namely, one can determine these properties from the properties of coherent Compton radiation.

    Axial vector transition form factors of $N\to \Delta$ in QCD

    A. Kucukarslan🇹🇷 · U. Ozdem🇹🇷 · A. Ozpineci🇹🇷

    The isovector axial vector form factors of $N\to \Delta$ transition are calculated by employing Light-cone QCD sum rules. The analytical results are analysed by both the conventional method, and also by a Monte Carlo based approach which allows one to scan all of the parameter space. The predictions are also compared with the results in the literature, where available. Although the Monte Carlo analysis predicts large uncertainties in the predicted results, the predictions obtained by the conventional analysis are in good agreement with other results in the literature.

    Weak-annihilation rare radiative decays of B-mesons

    Anastasiia Kozachuk🇷🇺

    In this talk, we present the predictions for a number of radiative decays $B_{(s)}\to V\gamma$, with the vector meson in the final state, which proceed through the weak-annihilation mechanism. Within the factorization approximation, we take into account the photon emission from the $B$-meson loop and from the vector-meson loop. The highest branching ratios for the weak-annihilation reactions reported here are $\mathcal{B}({\bar{B}}_s^0\to J/\psi \gamma )=1.5\cdot 10^{-7}$ and $\mathcal{B}(B^{-}\to {\bar{D}}_s^{\ast -}\gamma )=1.7\cdot 10^{-7}$, the estimated accuracy of these predictions being at the level of 20%.

    $K_0^{\ast }(800)$ as a companion pole of $K_0^{\ast }(1430)$

    Thomas Wolkanowski🇩🇪 · Milena Soltysiak🇵🇱 · Francesco Giacosa🇩🇪

    We study the light scalar sector up to $1.8$ GeV by using a quantum field theoretical approach which includes a single kaonic state in a Lagrangian with both derivative and non-derivative interactions. By performing a fit to $\pi K$ phase shift data in the $I=1/2,$ $J=0$ channel, we show that $K_0^{\ast }(800)$ (or $\kappa$) emerges as a dynamically generated companion pole of $K_0^{\ast }(1430)$. This is a result of investigating quantum fluctuations with one kaon and one pion circulating in the loops dressing $K_0^{\ast }(1430)$. We determine the position of the poles on the complex plane in the context of our approach: for $K_0^{\ast }(1430)$ we get $(1.413\pm 0.002)-i0.02cm(0.127\pm 0.003)$ (in GeV), while for $\kappa$ we get $(0.746\pm 0.019)-i0.02cm(0.262\pm 0.014)$ (in GeV). The model-dependence of these results and related uncertainties are discussed in the paper. A large-$N_c$ study confirms that $K_0^{\ast }(1430)$ is predominantly a quarkonium and that $K_0^{\ast }(800)$ is a molecular-like dynamically generated state.

    10 years of dark atoms of composite dark matter

    M. Yu. Khlopov🇫🇷

    In 2005 Sheldon Glashow has proposed his sinister model, opening the path to composite-dark-matter scenarios, in which heavy stable electrically charged particles bound in neutral atoms play the role of dark matter candidates. Though the general problem of new stable single charged particles, forming with ordinary electrons anomalous isotopes of hydrogen, turned out to be unresolvable in Glashow's scenario, this scenario stimulated development of composite dark matter models, which can avoid the trouble of anomalous isotope overproduction. In the simplest case composite dark matter may consist of -2 charged particles, bound by ordinary Coulomb interaction with primordial helium in OHe dark matter model. The advantage and open problems of this model are discussed.

    Role of pion pole in hard exlusive meson leptoproduction

    Sergey Goloskokov🇷🇺

    We consider the pion pole contribution and transversity effects determined by the $H_T$ and ${\bar{E}}_T$ Generalized Parton Distributions (GPDs) which are essential in hard pseudoscalar and vector meson leptoproduction. We investigate spin effects in the $\omega$ and ${\rho }^0$ reactions. It is shown that the pion pole contribution is very important in the $\omega$ production. Such effects in the ${\rho }^0$ channel are much smaller. Our results on spin asymmetries and spin density matrix elements in these reactions were found to be in good agreement with HERMES data.

    Neutrinoless double beta decay in the left-right symmetric models for linear seesaw

    Pei-Hong Gu🇨🇳

    In a class of left-right symmetric models for linear seesaw, a neutrinoless double beta decay induced by the left- and right-handed charged currents together will only depend on the breaking details of left-right and electroweak symmetries. This neutrinoless double beta decay can reach the experimental sensitivities if the right-handed charged gauge boson is below the 100 TeV scale.

    Axial form factors of the octet baryons in a covariant quark model

    G. Ramalho🇧🇷 · K. Tsushima🇧🇷

    We study the weak interaction axial form factors of the octet baryons, within the covariant spectator quark model, focusing on the dependence of four-momentum transfer squared, Q^2. In our model the axial form factors G_A(Q^2) (axial-vector form factor) and G_P(Q^2) (induced pseudoscalar form factor), are calculated based on the constituent quark axial form factors and the octet baryon wave functions. The quark axial current is parametrized by the two constituent quark form factors, the axial-vector form factor g_A^q(Q^2), and the induced pseudoscalar form factor g_P^q(Q^2). The baryon wave functions are composed of a dominant S-state and a P-state mixture for the relative angular momentum of the quarks. First, we study in detail the nucleon case. We assume that the quark axial-vector form factor g_A^q(Q^2) has the same function form as that of the quark electromagnetic isovector form factor. The remaining parameters of the model, the P-state mixture and the Q^2-dependence of g_P^q(Q^2), are determined by a fit to the nucleon axial form factor data obtained by lattice QCD simulations with large pion masses. In this lattice QCD regime the meson cloud effects are small, and the physics associated with the valence quarks can be better calibrated. Once the valence quark model is calibrated, we extend the model to the physical regime, and use the low Q^2 experimental data to estimate the meson cloud contributions for G_A(Q^2) and G_P(Q^2). Using the calibrated quark axial form factors, and the generalization of the nucleon wave function for the other octet baryon members, we make predictions for all the possible weak interaction axial form factors G_A(Q^2) and G_P(Q^2) of the octet baryons. The results are compared with the corresponding experimental data for G_A(0), and with the estimates of baryon-meson models based on SU(6) symmetry.

    Production of Inert Scalars at the high energy $e^{+}{e}^{-}$ colliders

    Majid Hashemi🇮🇷 · Maria Krawczyk🇵🇱 · Saereh Najjari🇵🇱 · Aleksander F. Żarnecki🇵🇱

    We investigate the phenomenology of the light charged and neutral scalars in Inert Doublet Model at future $e^{+}{e}^{-}$ colliders with center of mass energies of 0.5 and 1 TeV, and integrated luminosity of 500~fb${}^{-1}$. The analysis covers two production processes, $e^{+}{e}^{-}\to H^{+}{H}^{-}$ and $e^{+}{e}^{-}\to AH$, and consists of signal selections, cross section determinations as well as dark matter mass measurements. Several benchmark points are studied with focus on $H^{\pm }\to W^{\pm }H$ and $A\to ZH$ decays. It is concluded that the signal will be well observable in different final states allowing for mass determination of all new scalars with statistical precision of the order of few hundred MeV.

    A major new release of the Monte Carlo event generator Herwig++ (version 3.0) is now available. This release marks the end of distinguishing Herwig++ and HERWIG development and therefore constitutes the first major release of version 7 of the Herwig event generator family. The new version features a number of significant improvements to the event simulation, including: built-in NLO hard process calculation for all Standard Model processes, with matching to both angular-ordered and dipole shower modules via both subtractive (MC@NLO-type) and multiplicative (Powheg-type) algorithms; QED radiation and spin correlations in the angular ordered shower; a consistent treatment of perturbative uncertainties within the hard process and parton showering. Several of the new features will be covered in detail in accompanying publications, and an update of the manual will follow in due course.

    Testing R-parity with Geometry

    Yang-Hui He🇬🇧 · Vishnu Jejjala🇿🇦 · Cyril Matti🇬🇧 · Brent D. Nelson🇺🇸

    We present a complete classification of the vacuum geometries of all renormalizable superpotentials built from the fields of the electroweak sector of the MSSM. In addition to the Severi and affine Calabi-Yau varieties previously found, new vacuum manifolds are identified; we thereby investigate the geometrical implication of theories which display a manifest matter parity (or R-parity) via the distinction between leptonic and Higgs doublets, and of the lepton number assignment of the right-handed neutrino fields. We find that the traditional R-parity assignments of the MSSM more readily accommodate the neutrino see-saw mechanism with non-trivial geometry than those superpotentials that violate R-parity. However there appears to be no geometrical preference for a fundamental Higgs bilinear in the superpotential, with operators that violate lepton number, such as \nu H\bar{H}, generating vacuum moduli spaces equivalent to those with a fundamental bilinear.

    Pion Production via Proton Synchrotron Radiation in Strong Magnetic Fields in Relativistic Field Theory: Scaling Relations and Angular Distributions

    Tomoyuki Maruyama🇯🇵 · Myung-Ki Cheoun🇰🇷 · Toshitaka Kajino🇯🇵 · Grant J. Mathews🇺🇸

    We study pion production by proton synchrotron radiation in the presence of a strong magnetic field when the Landau numbers of the initial and final protons are $n_{i,f}\sim 10^4-10^5$. We find in our relativistic field theory calculations that the pion decay width depends only on the field strength parameter which previously was only conjectured based upon semi-classical arguments. Moreover, we also find new results that the decay width satisfies a robust scaling relation, and that the polar angular distribution of emitted pion momenta is very narrow and can be easily obtained. This scaling implies that one can infer the decay width in more realistic magnetic fields of $10^{15}$G, where $n_{i,f}\sim 10^{12}-10^{13}$, from the results for $n_{i,f}\sim 10^4-10^5$. The resultant pion intensity and angular distributions for realistic magnetic field strengths are presented and their physical implications discussed.

    Ab-initio calculations of charge symmetry breaking in the A=4 hypernuclei

    We report on ab-initio NCSM calculations of the A=4 mirror Lambda hypernuclei Lambda-4H and Lambda-4He, using the Bonn-Juelich LO chiral EFT YN potentials plus a CSB Lambda0--Sigma0 mixing vertex. In addition to reproducing rather well the 0+ (g.s.) and 1+ (exc.) binding energies, these four-body calculations demonstrate for the first time that the observed CSB splitting of mirror levels, reaching hundreds of keV for 0+ (g.s.), can be reproduced using realistic theoretical interaction models, although with a non-negligible momentum cutoff dependence. Our results are discussed in relation to recent measurements of the Lambda-4H (0+ g.s.) binding energy [MAMI A1 Collaboration, Phys. Rev. Lett. 114, 232501 (2015)] and the Lambda-4He (1+ exc.) excitation energy [J-PARC E13 Collaboration, Phys. Rev. Lett. 115, 222501 (2015)].

    Generalization of the Randall-Sundrum solution

    A.V. Kisselev🇷🇺

    The generalization of the Randall-Sundrum solution for the warp factor exp[sigma(y)] in the scenario with one extra coordinate y, non-factorizable space-time geometry and two branes isobtained. It is shown that the function obtained sigma(y) is symmetric with respect to an interchange of two branes. It also obeys the orbifold symmetry y -> - y and explicitly reproduces jumps of its derivative on both branes. This solution is defined by the Einstein-Hilbert's equations up to a constant C. It is demonstrated that different values of C results in theories with quite different spectra of the Kaluza-Klein gravitons.
