Measurement of $CP$ violation observables in $D^{+}\to K^{-}{K}^{+}\ddot{I}{€}^{+}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1112

A search for violation of the charge-parity $CP$ symmetry in the $D^{+}\to K^{-}{K}^{+}\ddot{I}{€}^{+}$ decay is presented, with proton-proton collision data corresponding to an integrated…
