QCD aspects of exclusive B meson decays
Abstract
I review recent progress on understanding QCD dynamics involved in exclusive B meson decays. Different frameworks, including light-cone sum rules, QCD factorization, perturbative QCD, soft-collinear effective theory, light-front QCD, are discussed. Results from lattice QCD are quoted for comparison. I point out the important issues in the above QCD methods, which require further investigation.
