QCD aspects of exclusive B decays
Description
We review QCD approaches to exclusive B meson decays, concentrating on QCD-improved factorization and perturbative QCD. The ideas of soft-collinear effective theory and light-cone sum rules are briefly explained. We discuss the recently measured time-dependent CP asymmetry of the Bd0 → π+π- modes, from which the unitarity angle can be extracted. (author)
