B Physics and CP Violation

Abstract

After an introduction to the Standard-Model description of CP violation and a brief look at the present status of this phenomenon in the kaon system, a classification of non-leptonic B-decays is given and the formalism of $B^0_{d,s}$--$\bar{B^0_{d,s}}$ mixing is discussed. We then turn to the $B$-factory benchmark modes, CP violation in charged B decays, and the $B_s$-meson system. Finally, we focus both on $B\toπK$ decays, which play an important role to probe the CKM angle $γ$, and on the $B_d\toπ^+π^-$, $B_s\to K^+K^-$ system, which allows an interesting determination of $β$ and $γ$.
