Amplitude analysis and branching fraction measurement of the decay $D_s^{+}\to K^{+}{\pi }^{+}{\pi }^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +560

Using $6.32$ fb${}^{-1}$ of $e^{+}{e}^{-}$ collision data collected at the center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysi…
