Search for $CP$ violation in $D^{+}\to \ddot{I}•\ddot{I}{€}^{+}$ decays

LHCb collaboration, R. Aaij, M. Abdelfatah +1106

A search for charge-parity ($CP$) violation in the Cabibbo-suppressed $D^{+}\to \ddot{I}•\ddot{I}{€}^{+}$ decay is presented, using proton-proton collision data corresponding to an integrated lumin…
