QCD Factorization for B {r_arrow} {pi} {pi} Decays: Strong Phases and CP Violation in the Heavy Quark Limit
Abstract
We show that, in the heavy quark limit, the hadronic matrix elements that enter B meson decays into two light mesons can be computed from first principles, including {open_quotes}nonfactorizable{close_quotes} strong interaction corrections, and expressed in terms of form factors and meson light-cone distribution amplitudes. The conventional factorization result follows in the limit when both power corrections in 1/m{sub b} and radiative corrections in {alpha}{sub s} are neglected. We compute the order-{alpha}{sub s} corrections to the decays B{sub d}{r_arrow}{pi}{sup +}{pi}{sup {minus}} , B{sub d}{r_arrow}{pi}{sup 0}{pi}{sup 0} , and B{sup +}{r_arrow}{pi}{sup +}{pi}{sup 0} in the heavy quark limit and briefly discuss the phenomenological implications for the branching ratios, strong phases and {ital CP } violation. {copyright} {ital 1999} {ital The American Physical Society}
