Abstract

We report measurements of time-dependent CP asymmetries related to the CKM angle $\beta/\phi_1$, using decays of neutral B mesons to charmonium, open charm and in $b\to s$ loop processes. A preliminary measurement of time-dependent CP asymmetries in $B^0\to \rho^0(770) K^0_S$ decays from the BaBar experiment is given here.
