Measurements of CP observables in B± → D K± and B± → D π± decays are presented where the D meson is reconstructed in the final states K± π∓, π± K∓, K+ K−, π+ π−, K± π∓ π+ π−, π± K∓ π+ π− and π+ π− π+ π−.

Abstract

Measurements of CP observables in B± → D K± and B± → D π± decays are presented where the D meson is reconstructed in the final states K± π∓, π± K∓, K+ K−, π+ π−, K± π∓ π+ π−, π± K∓ π+ π− and π+ π− π+ π−. This analysis uses a sample of charged B mesons from pp collisions collected by the LHCb experiment in 2011 and 2012, corresponding to an integrated luminosity of 3.0 fb^−1. Various CP-violating effects are reported and together these measurements provide important input for the determination of the unitarity triangle angle γ. The analysis of the four-pion D decay mode is the first of its kind.
