Amplitude analysis and branching fraction measurement of $$ {D}_s^{+} $$ → K−K+π+π+π−
A bstract Using e + e − annihilation data corresponding to a total integrated luminosity of 6 . 32 fb − 1 collected at the center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysis of the decay $$ {D}_s^{+} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msubsup> …
