英文摘要: We investigate the pure penguin process B- -> pi(-)phi using the QCD factorization approach to calculate hadronic matrix elements to the alpha(s) order in some well-known NP models. It is shown that the NP contributions in R-parity conserved SUSY models and 2HDMs are not enough to make the branching ratios of B -> pi phi as large as their experimental upper bounds. We have shown that the bounds can be reached in the flavor changing Z' models under all relevant experimental constraints. (c) 2007 Published by Elsevier B.V.
