Observation of the Isospin-Violating Decay $D_s^{*+}\to D_s^+π^0$

Description

Using data collected with the CLEO~II detector, we have observed the isospin-violating decay $D_s^{*+}\to D_s^+π^0$. The decay rate for this mode, relative to the dominant radiative decay, is found to be $Γ(D_s^{*+}\to D_s^+π^0)/Γ(D_s^{*+}\to D_s^+γ)= 0.062^{+0.020}_{-0.018}\pm0.022$.
