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.

abstract
We use the relativistic light--front quark model to show that both strong and radiative $D^\ast$ decays are in good agreement with the 1992 CLEO II results. In particular the coupling for $D^{\ast}\ra D \pi$ is consistent with the experimental upper limit. The key point is the relativistic treatment of the quark spin.

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.
