CP Violation in the B System: Status and Perspectives

In this decade, the exploration of CP violation is governed by the B-meson system, where non-leptonic decays play an outstanding rôle. To set the stage, we have first a look at the main strategies to circumvent the calculation of the relevant hadronic matrix elements in these studies, and discuss popular avenues for physics beyond the Standard Model to enter the roadmap of quark-flavour physics. We are then well prepared to analyze puzzles in the data for B → φK and B → πK decays, and to discuss b → d penguin processes, which represent a new territory for the Bfactory studies. Finally, we turn to the physics potential of the Bs-meson system, which can be fully exploited at the LHC. Invited talk at the GUSTAVOFEST Symposium in Honour of Gustavo C.
