Colored-hadron distribution in hadron scattering in SU(2) lattice QCD

Colored-hadron distribution in hadron scattering in SU(2) lattice QCD

In color SU(2) lattice QCD, we investigate colored-diquark distributions in two-hadron scatterings by means of Bethe-Salpeter amplitudes on the lattice. With colored-diquark operators in the Coulomb gauge, we measure components of two colored diquarks realized as intermediate states via one-gluon-ex...

Zusammenfassung:In color SU(2) lattice QCD, we investigate colored-diquark distributions in two-hadron scatterings by means of Bethe-Salpeter amplitudes on the lattice. With colored-diquark operators in the Coulomb gauge, we measure components of two colored diquarks realized as intermediate states via one-gluon-exchange processes in hadron scattering. From the colored-diquark distributions, we estimate the dominant range of gluon (color) exchanges between two closely located hadrons. We find that the colored-diquark components are enhanced at the short range (
