Abstract

A first study of CP violation in the decay modes B± [K_S ⁰Kπ^±]Dh^±and B^±[K_S ⁰Kπ^±]Dh^±, where h labels a K or p meson and D labels a D0 or D⁰meson, is performed. The analysis uses the LHCb data set collected in pp collisions, corresponding to an integrated luminosity of 3 fb^-1. The analysis is sensitive to the CP-violating CKM phase γ through seven observables: one charge asymmetry in each of the four modes and three ratios of the charge-integrated yields. The results are consistent with measurements of γ using other decay modes.
