Abstract

We calculate the rate for D_s^* → D_s π⁰ decay using Chiral Perturbation Theory. This isospin violating process results from π⁰ - η mixing, and its amplitude is proportional to (m_d - m_u)/(m_s-(m_u+m_d)/2 ). Experimental information on the branching ratio for D_s^* → D_s π⁰ can provide insight into the pattern of SU(3) violation in radiative D^* decays.
