SPECTROSCOPY OF DOUBLY CHARMED BARYONS: $\Xi_{cc}^+$ AND $\Xi_{cc}^{++}$

Abstract

Using the quark–diquark approximation in the framework of Buchmüller–Tye potential model, we investigate the spectroscopy of doubly charmed baryons:[Formula: see text] and [Formula: see text]. Our results include the masses, parameters of radial wave functions of states with different excitations of both diquark and light quark–diquark system. We calculate the values of fine and hyperfine splittings of these levels and discuss some new features, related to the identity of heavy quarks, in the dynamics of hadronic and radiative transitions between the states of these baryons.
