Decays of Charmed Vector Mesons --- eta-pi^0 mixing as an origin of isospin non-conservation ---

Abstract

Pion emitting decays and radiative ones of D^{*+,0} and D_s^{*+} are studied. As the result, the full-width of D^{*0} is predicted, by assuming the isospin symmetry. In addition, the isospin non-conserving D_s^{*+} --> D_s^+ pi^0 decay is investigated under the assumption that it proceeds through the eta-pi^0 mixing.
