A study of CP violation in B± → DK± and B± → Dπ± decays with D→KS0K±π∓ final states

A first study of CP   violation in the decay modes B±→[KS0K±π∓]Dh± and B±→[KS0K∓π±]Dh±, where h labels a K or π meson and D   labels a D0D0 or D‾0 meson, 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.
