摘要
Using the soft-collinear effective theory we derive the factorization theorem for the decays B-->M1M2 with M-1,M-2=pi,K,rho,K-*, at leading order in Lambda/E-M and Lambda/m(b). The results derived here apply even if alpha(s)(E(M)Lambda) is not perturbative, and we prove that the physics sensitive to the ELambda scale is the same in B-->M1M2 and B-->M form factors. We argue that c (c) over bar penguins could give long-distance effects at leading order. Decays to two transversely polarized vector mesons are discussed. Analyzing B-->pipi we find predictions for B-0-->pi(0)pi(0) and |V-ub|f(+)(B-->pi)(0) as a function of gamma.
