Heavy Flavour Physics
Abstract
Description
The current status of the theory and phenomenology of weak decays of hadrons containing a heavy quark is reviewed. Exclusive semileptonic and rare decays of $B$ mesons are discussed, as well as inclusive decay rates, the semileptonic branching ratio of the $B$ meson, and the lifetimes of $b$-flavoured hadrons. Determinations of $α_s$ from $Υ$ spectroscopy are briefly presented.
27 pages, 7 figures, discussion of the theory of the B semileptonic branching ratio has been revised
