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