WEAK RADIATIVE DECAYS OF PSEUDOSCALAR CHARMED MESONS

Abstract

We consider here radiative weak decays of charmed mesons such as [Formula: see text] and [Formula: see text] in a quark model where in general a translationally invariant SU(6) hadronic state is described by constituent quark field operators satisfying equal time algebra and a harmonic oscillator wave function. The model had its earlier success during its application to a variety of hadronic phenomena, and here also, without any free parameters, it calculates the branching ratios as [Formula: see text] and [Formula: see text]. Such calculations are very close to the estimations of Asthana and Kamal, and thus is consistent with the QCD enhancement of the latter branching ratio with respect to the former.
