A first study of CP violation in the decay modes B± → [K0S K± π∓]_D h± and B± → [K0S K∓ π±]_D h±, where h labels a K or π meson and D labels a D0 or anti-D0 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.

Abstract

A first study of CP violation in the decay modes B± → [K0S K± π∓]_D h± and B± → [K0S K∓ π±]_D h±, where h labels a K or π meson and D labels a D0 or anti-D0 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.
