Strong and Electromagnetic Mass Splittings in Heavy Mesons

Abstract

The contributions to heavy meson mass differences by the strong hyperfine interaction, the light quark masses and the electromagnetic interaction are obtained from the empirical values of the $D$, $D^{\ast }$, $B$ and $B^{\ast }$ masses by means of a mass formula based on the heavy quark mass expansion. The three different types of contributions are determined with significant accuracy to next to leading order in that expansion.
