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

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

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

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

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

Description:
The GlueX experiment at Jefferson Lab has been designed to study photoproduction reactions with a 9-GeV linearly polarized photon beam. The energy and arrival time of beam photons are tagged using a s
