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

    hep-ph 2025-11 unverdicted novelty 5.0

    Light-cone sum rules yield radiative decay widths for ground-state vector mesons that match data where available and exhibit a universal linear dependence on a function A(x) in log coordinates arising from decay-const...
