Theory of hadronic B decays
arXiv:hep-ph/0502141 · doi:10.1016/j.nuclphysbps.2006.02.139
Abstract
I give an overview of the theory of hadronic nonleptonic B decays into two light mesons. Using the soft-collinear effective theory (SCET), a factorization theorem for these processes has been proven to leading order in 1/mb. The phenomenological implications of this factorization relation for B-> ππdecays are discussed, together with the prospects for determining the weak phase α(ϕ_2) from these modes.
