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 s=7TeV 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.
