Studies of the decay $D_s^{+}\to K^{+}{K}^{-}{\mu }^{+}{\nu }_{\mu }$

BESIII Collaboration, M. Ablikim, M. N. Achasov +608

The $D_s^{+}\to K^{+}{K}^{-}{\mu }^{+}{\nu }_{\mu }$ decay is studied based on 7.33 fb${}^{-1}$ of $e^{+}{e}^{-}$ collision data collected with the BESIII detector at center-of-mass energies in the range from 4.12…
