Chiral imbalance: its manifestation in meson decays. Instability of chiral charge density, possible generation by Schwinger effects
We will discuss how to solve the Odderon problem in perturbative QCD and its relation to open spin chains in the N=4 super Yang-Mills theory.
Some latest Run II CMS results on Higgs measurements and Beyond the Standard Model physics searches are reviewed
Latest results from LHCb experiment will be presented
The talk will be on behalf of the LHCb CollaborationThe LHCb experiment is designed to study heavy hadrons produced in proton-proton collisions at the LHC. Charmed and beauty hadrons produced in the pp-collision are studied to identify new states, confirming or disproving those recently claimed, and establishing their quantum numbers. The latest results on heavy baryon decays based on the data...
We present the recent results on the confinement/deconfinement transition in lattice SU(2) QCD with two flavors of quarks at finite quark density and zero temperature. In the region μq ∼ 1000 MeV we observe the confinement/deconfinement transition which manifests itself in rising of the Polyakov loop and vanishing of the string tension σ. After the deconfinement is achieved at μq > 1000 MeV...
Brief review of the proton radius problem is given. In the framework of the quasipotential method in quantum electrodynamics we calculate the contribution of light pseudoscalar (PS) and axial-vector (AV) mesons to the interaction operator of a muon and a proton in muonic hydrogen atom. The coupling of mesons with the muon is via two-photon intermediate state. The parametrization of the...
I will discuss the present status of the determination of the proton radius. Starting with 2010 there is a controversy within the results obtained from electron-proton scattering, hydrogen and deuterium spectroscopy and spectroscopy of muonic hydrogen and deuterium.I will briefly review the situation and its recent development.
The exotic hadrons, those, which have content beyond the conventional scheme of mesons, consisting of a quark and an antiquark, and baryons, consisting of three quarks, were predicted with the quark model itself. However first observation of an exotic candidate was made only less than 15 years ago. Since then quite a number of exotic-like states was discovered and some of them were proved to...
Recent results of the LHCb experiment in the charm physics field will be presented. The contribution will cover spectroscopy of the charmed particles, search for there rare decays, as well as for CP violation effects in charm sector.
Results from ALICE Cosmic Ray Physics program and MATHUSLA Experiment Proposal
The derivation of the BFKL equation based on the unitarity relations is strongly complicated in the next-to-next-to-leading logarithmic approximation. The main reason of the complification is appearance of Regge cuts in amplitudes with gluon quantum numbers in the cross channels and negative signature.
A new kinematic regime for the vertex functions of gauge theories is discussed
I will present the latest results from the ATLAS experiment on measurements of the Standard Model and Higgs boson production processes.
CMS data at 13 TeV for electroweak Z boson production with associated hadronic jets are presented. The measurement is based on data recorded in 2016 by the CMS experiment at the LHC corresponding to an integrated luminosity of 35.9 fb−1. The measured cross section is in agreement within the experimental uncertainties with the standard model predictions in the leading order approximation.
Search for asymptotic BFKL effects at CMS in dijet events with large rapidity separation between jets in proton-proton collisions at 7 TeV is presented. CMS data on cross-section ratios and azimuthal decorrelations for dijets with large rapidity separation between jets are compared with predictions by various Monte Carlo event generators based on DGLAP and BFKL evolutions.
We present highlights of recent studies by ALICE on energy and system size dependence of multi-particle production in pp, p-Pb and A-A collisions at various energies, investigations of production of light nuclei, including exotic states of hypernuclei, new flow-like effects and collective phenomena in small systems, long-range correlations in hadron collisions at the LHC, as well as the...
Results of a new analysis of negative charged particle yields in $Au+Au$ collisionsas a function of transverse momentum obtained by the STAR Collaboration for the first phase of the RHIC Beam Energy Scan Program in the framework of the $z$-scaling approach are presented.The spectra were measured over a wide range of collision energy $sqrt {s_{NN}}~=~7.7-200$~GeV and transverse momentum of...
The PHENIX experiment at the relativistic heavy ion collider (RHIC) has finished data taking in 2016. However, a huge amount of data on p+p, p+A and A+A collisions taken at different collision energies in the last years of the detector operation is actively analysed by the collaboration and brings a wealth of new experimental results. In this talk, we present review of the most recent PHENIX...
A semiphenomenological variant of the construction of the QCD Hamiltonian on the light front in the light front gauge is considered. This Hamiltonian is intended to describe the hadronic states constructed from "effective" quarks and gluons on the light front. Such Hamiltonian provides confinement for the quark-antiquark state both in the transverse direction and in the longitudinal...
Three nucleon system(triton) was considered. Relativistic properties of this system were investigated. For this relativistic generalization of Faddeev approach was used. As two particle T-matrix which contained in relativistic Faddeev equation we used solution of Bethe-Salpeter equation. So eventually we had Bethe-Salpeter-Faddeev(BSF) equation for describe three nucleon system. As potential...
Experimental data on $pi N $ scattering in the elastic energy region $W leq 1.45 GeV $ are analyzed within the $K$-matrix approach with effective Lagrangians. The charge splitting in $delta^{++}_{33}$ and $delta^{0}_{33}$ phases obtained in the phase shift analysis is studied . It is shown that the change in the sign in the energy dependence of the phase difference can be obtained with...
