Strong and Radiative $D^\ast$ Decays

High Energy Physics - Phenomenology 2011-07-19 v1

Abstract

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