Description
The standard way to measure the CP phases $2\beta$ and $2\beta_s$ uses $B_{d,s}$ decays into charmonium. The theoretical precision is limited by the unknown penguin contribution to the decay amplitude. I show that this contribution can be expressed in terms of the same matrix elements which
constitute to the dominant tree amplitude. The second part of my talk
addresses a global analysis of D meson decays into two pseudoscalar mesons and the predictions of CP asymmetries.
