Abstract

An analysis of B±→DK± and B±→Dπ± decays is presented where the D meson is reconstructed in the two-body final states: K±π∓, K+K− and π+π−. Using 1.0 fb−1 of pp collisions, measurements of several observables are made including the first observation of the suppressed mode B±→[π±K∓]DK±. CP violation in B±→DK± decays is observed with 5.8σ significance.
