英文摘要: We investigate the pure penguin decays B --> piphi in the Standard Model (SM) and in the Constrained Minimal Supersymmetric Standard Model (CMSSM) using the QCD factorization approach and consider the Sudakov effects in the twist-3 contribution. We find Br(B- --> pi(-)phi)=(1.95-5.70)x 10(-9) in SM and (1.1-2.4) x 10(-8) in CMSSM with large tan beta which is about one order of magnitude larger than that in SM. (C) 2003 Elsevier Science B.V.
