CP Violation and B Physics at the LHC

Abstract

In this decade, there are huge efforts to explore B-meson decays, which provide an interesting playground for stringent tests of the Standard-Model description of the quark-flavour sector and the CP violation residing there. Thanks to the $e^{+}{e}^{-}$ B factories at KEK and SLAC, CP violation is now a well-established phenomenon in the B-meson system, and recently, also $B_s^0$--${\bar{B}}_s^0$ mixing could be measured at the Tevatron. The decays of $B_s^0$ mesons are the key target of the B-physics programme at the LHC, and will be the focus of this presentation, discussing the theoretical aspects of various benchmark channels and the question of how much space for new-physics effects in their observables is left by the recent experimental results.
