Type: статьи в журналах
Date: 2021
Description: We systematically study two-body nonleptonic decays of light lambda hyperon Λ→pπ−(nπ0) with account for both short- and long-distance effects. The short-distance effects are induced by five topologies ... More

Description: In the semileptonic decays of heavy mesons and baryons, the lepton-mass dependence factors out in the quadratic cos2θ coefficient of the differential cosθ distribution. We call the corresponding norma ... More

Description: We study the gluon parton densities [parton distribution functions (PDFs), transverse momentum distributions (TMDs), generalized parton distributions (GPDs)] and form factors in soft-wall AdS/QCD. We ... More

Description: We report a measurement of the π− photoproduction beam asymmetry for the reaction →γp→π−Δ++ using data from the GlueX experiment in the photon beam energy range 8.2–8.8 GeV. The asymmetry Σ is measure ... More

Description: We discuss new ideas for consideration of loop diagrams and angular integrals in D-dimensions in QCD. In case of loop diagrams, we propose the covariant formalism of expansion of tensorial loop integr ... More

Description: It is shown that the basic shape of dipion and KK̅ mass spectra in decays J/ψ→ϕ(ππ,KK̅), ψ (2S)→J/ψππ, Y(4260)→J/ψ π π and in the two-pion transitions of bottomonia states are explained by an unified ... More

Date: 2018
Description: We present an improved study of the electromagnetic form factors of the nucleon and of the Roper-nucleon transition using an extended version of the effective action of soft-wall AdS/QCD. We include n ... More

Description: We use the present upper bound on the neutron electric dipole moment to give an estimate for the upper limit of the CP-violating couplings of the η(η′) to the neutron. Using this result, we derive con ... More

Description: The basic shape of di-pion mass spectra in the two-pion transitions of both charmonia and bottomonia states is explained by a unified mechanism based on contributions of the ππ, KK̅, and ηη coupled ch ... More
