Description

The decay of any higher $c\bar{s}$ meson to $D_{s}^{+}\pi^{0}$ violates isospin conservation, thus small partial width. Some theoretical models suggest $D_{s}^{*+} \to D_{s}^{+}\pi^{0}$ proceed via $\pi^{0} - \eta$ mixing to conserve isospin but including such consideration also, the radiative decay $D_{s}^{*+} \to D_{s}^{+}\gamma$ is still expected to dominate. The Belle II detector provides an opportunity to improve previous measurements with higher data statistics and improved detector performance. In this presentation, we present the feasibility to study the measurements of the ratio of partial widths $\Gamma(D_{s}^{*+} \to D_{s}^{+}\pi^{0})/\Gamma(D_{s}^{*+} \to D_{s}^{+}\gamma)$.
