Abstract
Measurements of branching fractions and CP asymmetries of B− → D0K− modes allow a theoretically clean extraction of the CKM angle γ. The method proposed by Atwood, Dunietz and Soni makes use of doubly Cabibbosuppressed decay modes, which produce large CP-violating effects. The CDF experiment reports the first measurement at a hadron collider of branching fractions and CP asymmetries of both DCS B → Dπ/K signals. Using 5.0 fb−1 of data we found a combined significance exceeding 5σ and we determined the physics parameters with accuracy comparable with b factories.
