Bottomonium and Charmonium spectrum from the Momentum Space Relativistic Schrodinger Equation

We use the momentum-space relativistic Schrodinger equation to fit the bottomonium and charmonium mass spectra. We use the usual, linear plus Coulomb-type potentials and also linear plus Yukawa potentials besides the spin-spin and spin-orbit potentials. The singularities in the linear and Coulomb potentials in momentum space are handled by well-known subtraction methods. We will present the fitted spectra, parameters, and decay rates.
