Theoretical review of B-physics

Weak decays and mixing of B-hadrons play a special role in our understanding of the physics of the Standard Model and beyond. The measured amplitudes, however, result from a complicated interplay of weak and strong interaction effects. Understanding strong interaction dynamics, which becomes simpler for heavy quarks, is thus a fundamental part of the game. In this review, several theoretical aspects of B dynamics which are relevant for current and future experimental measurements are discussed.
