Using B_d⁰, B_s⁰ Decays at Hadronic B-Factories to Determine CP Angles alpha and beta

At the first PPPP workshop, I gave a review talk on physics of B and CP-phases. In my talk, I explained DRG method and our extension to extract CP angles $\alpha$ and $\gamma$ from measurements of the decay rates of $B_{d,s}^0 \to \pi\pi, \pi K, K K$. There are several advantages to this extension: discrete ambiguities are removed, fewer assumptions are necessary, and the method works even if all strong phases vanish. I also talked on several other topics.
