Abstract

The starting point of these lectures is an introduction to th e weak interactions of quarks and the Standard-Model description of CP violation, where the central role is play ed by the Cabibbo-Kobayashi-Maskawa matrix and the corresponding unitarity triangles. Since the B -meson system governs the stage of (quark) flavour physics an d CP violation, it is our main focus: we shall classify B -meson decays, introduce the theoretical tools to deal with them, investigate the requirements for non-vanishing CP-violating asymmetries, and discuss the main strategies to explore CP violation and the preferred avenues for physics b eyond the Standard Model to enter. This formalism allows us then to discuss important benchmark modes, where we will also address the question of how much space for new-physics effects in the B studies at the LHC is left by the recent experimental results from the B factories and the Tevatron.
