Description

We report on a time-dependent CP violation measurement of B0->D_CP($\star$)h0 decays, where the light neutral hadron h0 is a pi0, eta, or omega meson, and the neutral D meson is reconstructed in decays to two-body CP eigenstates K+ K-, K_S pi0, or K_S omega. The measurement is performed by combining the final data samples of 471 million BBbar pairs collected by the BABAR experiment and 772 million BBbar pairs collected by the Belle experiment. A first observation of CP violation in B0->D_CP(*)h0 decays governed by mixing-induced CP violation in terms of sin(2beta) [sin(2phi_1)] is presented.
