Measurement of the Born cross section for $e^{+}{e}^{-}\to p{K}^{-}{K}^{-}\bar{\hat{I}}{ž}^{+}$ at $\sqrt{s}=$ 3.5-4.9 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +695

Using $e^{+}{e}^{-}$ collision data corresponding to a total integrated luminosity of 20 ${\mathrm{fb}}^{-1}$ collected with the BESIII detector at the BEPCII collider, we present a measurem…
