# A study of CP violation in B±→DK± and B±→Dπ± decays with D→K0SK±π∓ final states

LHCb Collaboration; Bernet, R; Müller, K; Steinkamp, O; Straumann, U; Vollhardt, A; et al (2014). A study of CP violation in B±→DK± and B±→Dπ± decays with D→K0SK±π∓ final states. Physics Letters B, 733:36-45.

## Abstract

A first study of CP violation in the decay modes B±→[K0SK±π∓]Dh± and B±→[K0SK∓π±]Dh±, where h labels a K or π meson and D labels a D0 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.
