Potential model calculations and predictions for $\bm c\bar{\bm s}$ quarkonia
Abstract
We investigate the spectroscopy and decays of the charm-strange quarkonium system in a potential model consisting of a relativistic kinetic energy term, a linear confining term including its scalar and vector relativistic corrections and the complete perturbative one-loop quantum chromodynamic short distance potential. The masses and wave functions of the various states are obtained using a variational technique, which are then used in a perturbative treatment of the potential to find the mass spectrum of the system and radiative decay widths. Our results compare well with the available data for the spectrum of states. We include a discussion of the effect of mixing and an investigation of the Lorentz nature of the confining potential.
