Abstract

In this proceeding, we report the recent measurements of time-dependent CP violation in B meson decays from the Belle Collaboration. The Belle experiment stopped operation in June 2010 and collected nearly 772 x 10⁶ B B-bar pairs at the Υ(4S) resonance at the KEKB asymmetric-energy e⁺e^- collider. We used this full data sample to measure the CP violation parameters in b->c c-bar s and b->c c-bar d decays. We also report new measurements of CPT violation parameters in B decays. Furthermore, we report the first observation of a new b->s radiative penguin decay B⁰->ϕK⁰ γ, as well as measurements of its time-dependent CP asymmetry.
