Observation of direct CP violation in the measurement of the Cabibbo-Kobayashi-Maskawa angle γ with B±→D(*)K(*)± decays

We report the determination of the Cabibbo-Kobayashi-Maskawa C P -violating angle γ through the combination of various measurements involving B ± → D K ± , B ± → D ∗ K ± , and B ± → D K * ± decays performed by the BABAR experiment at the PEP-II e + e − collider at SLAC National Accelerator Laborator...
