Amplitude analysis and branching fraction measurement of $D_s^{+}\to K^{-}{K}^{+}{\pi }^{+}{\pi }^0$

BESIII Collaboration

The first amplitude analysis of the decay $D_s^{+}\to K^{-}{K}^{+}{\pi }^{+}{\pi }^0$ is presented using the data samples, corresponding to an integrated luminosity of 6.32 fb${}^{-1}$, collected with t…
