Structure Calculations

Nucleon-structure calculations of isovector vector-and axialvector-current form factors, transversity and scalar charge, and quark momentum and helicity fractions are reported from two recent 2+1-flavor dynamical domain-wall fermions lattice-QCD ensembles generated jointly by the RIKEN-BNL-Columbia and UKQCD Collaborations with Iwasaki × dislocation-suppressing-determinatn-ratio gauge action at inverse lattice spacing of 1.378(7) GeV and pion mass values of 249.4(3) and 172.3(3) MeV.

The first radial excitations of axial-vector mesons are considered in the framework of the extended U(3) × U(3) Nambu–Jona-Lasinio model. We calculate the mass spectrum of a1, f1 and also strange axial-vector mesons. For description of radially excited states, we used the form factors of polynomial type of the second order in transverse quark momentum. For the ground- and excited-state mesons consisting of light quarks we have calculated the widths of a number of strong and radiative decays. We got satisfactory agreement with experimental data for the ground states. A set of predictions for the excited states of mesons is given.

We carry out a detailed analysis of effects of flavor dependence of average transverse quark momentum inside a meson onJ/ψ→Pandϒ→Bctransition form factors and two-body weak hadronic decays ofJ/ψandϒemploying the factorization scheme. We predict the branching ratios of semileptonic and nonleptonic weak decays ofJ/ψandϒmesons in Cabibbo-angle-enhanced and Cabibbo-angle-suppressed modes.
