Abstract: The higher state masses of the heavy pentaquarks ????c0,Nc0,Ξc0${\theta _{c}^{0}}, {N_{c}^{0}}, {{\Xi }_{c}^{0}}$ and ????b+,Nb+,Ξb+$\theta _{b}^{+}, N_{b}^{+}, {\Xi }_{b}^{+}$ have been investigated in diquark-diquark-antiquark configuration where the lightquarks combine to form a diquark and the… read more here.

Abstract: We calculate the leading-twist, helicity-independent generalized parton distributions (GPDs) of the proton, at finite skewness, in the Nambu–Jona-Lasinio (NJL) model of quantum chromodynamics (QCD). The NJL model reproduces low-energy characteristics of QCD, including dynamical chiral… read more here.

DOI: 10.1134/s1063778818030134
Abstract: Abstractfinite size of a doubly heavy diquark yields a positive correction to baryon masses calculated in the local-diquark approximation. Upon evaluating this correction for the ground states of doubly charmed baryons, it became possible to… read more here.
