Abstract

We calcuate the rate for

D_{s}^{*} \to D_{s} π^{0}

decay using chiral perturbation theory. This isospin-violating process results from

π^{0} - η

mixing, and its amplitude is proportional to

\frac{(m_{d} - m_{u})}{[\frac{m_{s} - (m_{u} + m_{d})}{2}]}

. Experimental information on the branching ratio for

D_{s}^{*} \to D_{s} π^{0}

can provide insight into the pattern of SU(3) violation in radiative

D^{*}

decays.
