Spin Splitting Spectroscopy of Heavy Quark and Antiquarks Systems

Phenomenological potentials describe the quarkonium systems like c�c, bb, and �bc where they give a good accuracy for the mass
spectra. In the present work, we extend one of our previous works in the central case by adding spin-dependent terms to allow
for relativistic corrections. By using such terms, we get better accuracy than previous theoretical calculations. In the present
work, the mass spectra of the bound states of heavy quarks c�c, b�b, and Bc mesons are studied within the framework of the
nonrelativistic Schrödinger equation. First, we solve Schrödinger’s equation by Nikiforov-Uvarov (NU) method. The energy
eigenvalues are presented using our new potential. The results obtained are in good agreement with the experimental data and
are better than the previous theoretical estimates.
