Measurement of branching fraction of $D_s^{\ast +}\to D_s^{+}{\pi }^0$ relative to $D_s^{\ast +}\to D_s^{+}\gamma$

BESIII Collaboration, M. Ablikim, M. N. Achasov +566

Based on 7.33 fb${}^{-1}$ of $e^{+}{e}^{-}$ collision data taken at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we measure the branching fraction of $D^{*…
