Bound Dirac states for pseudoscalar Cornell potential：3+1 dimensions

The Cornell potential consists of Coulomb and linear potentials, i.e.-a/r+br, that it has received a great deal of attention in particle physics. In this paper, we present exact solutions of the Dirac equation with the pseudoscalar Cornell potential under spin and pseudospin symmetry limits in 3+1 dimensions. The energy eigenvalues and corresponding eigenfunctions are given in explicit forms.
