Global analysis of charm mixing parameters and determination of the CKM angle gamma

We present an updated global analysis of beauty decays sensitive to the angle γ of the Cabibbo-Kobayashi-Maskawa matrix and of D-meson mixing data in the framework of approximate universality, in which CP violation in D-D¯ mixing is described in terms of two universal weak phases corresponding to dispersive and absorptive contributions. We extract the fundamental theoretical parameters determining absorptive and dispersive contributions to D meson mixing and CP violation, together with the angle γ. The results for the charm mixing parameters are x12≃x=(0.401±0.043)% and y12≃y=(0.610±0.017)%, while the two CP-violating phases are given by ϕ2M=(0.13±0.70)° and ϕ2Γ=(2.1±1.6)°. The angle γ is found to be γ=(65.7±2.5)°, in excellent agreement with the indirect determination from the unitarity triangle analysis.
