Abstract

The spectra of charmed hadrons ( c c ¯ and ccc baryons) and cc-diquarks are evaluated using a non-relativistic screened potential model. In this work, the central potential is composed of short-range coulomb-like and long-range screened confinement potential. Along with these, we have incorporated the O(1/m) corrections predicted from pNRQCD and lattice studies into the potential. We solve the non-relativistic Schrodinger equation numerically using the Matrix-Numerov method to evaluate the spectra of charmed hadrons. We interpret χc2(3930) and χc1(4140) as P-wave charmonium states and ψ2(3823) and ψ(4360) as D-wave charmonium states. The masses of triply charmed baryons are evaluated within the quark-diquark approach. Various radial and orbital excitations of the diquarks and the diquark-quark systems have been considered in this work. We have also carried out a sensitivity analysis of the model parameters for S-wave charmonium states to determine the sensitivity of mass spectra on the model parameters.
