The status of CP violation and the CKM matrix is reviewed. Direct CP violation in B decay has been established and the measurement of sin(2beta) in \psi K modes reached 5% accuracy. I discuss the implications of these, and of the possible…

The measurement of $\sin {2\beta}$ from $B_d \to J/\psi K_s$ does not resolve the discrete ambiguities in the angle $\beta$. A measurement of $\cos {2\beta}$ is therefore desirable.This talk is about measuring the CKM angle $\beta(\phi_1)$…
