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 $D$, $D^*$, $B$ and $B^*$ 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.

Relativistic effects in $\mbox{M1}$ radiative decays of heavy-light mesons
A relativistic potential model, with all parameters taken from meson masses, predicts M1 radiative widths for D and D_s mesons and gives a B_s hyperfine splitting close to the new CMS measurement.
