Abstract

Time-dependent CP violating phenomena probe the time evolution and the decay of beauty hadrons and allow access to the underlying dynamics. We present various time-dependent CP violation measurements in the B⁰ and Bs⁰ meson systems that are performed using pp collisions by LHCb and using e⁺ e⁻ collisions by the B factory experiments BaBar and Belle. For LHCb, we report measurements of the quantum-loop mediated Bs^{0 → (}K⁻ π^{+) (}K⁺ π⁻⁾ and Bs⁰ → φφ decays, and measurements of B⁰ → D^∓ π^± and Bs^{0 →h+} h⁻ decays. For Belle, we report new results for the charm-less B⁰ → π⁰ π⁰ K⁰S^andB0 → K⁰Sηγ decays. In addition, we present a measurement of cos 2β obtained by a time-dependent Dalitz plot analysis of B⁰ → D^∗h⁰ with D → K⁰S^π+π⁻ that combines the final BaBar and Belle data sets.
