Abstract:The presence of additional strong phase from power corrections and other chirally enhanced terms makes it more difficult to predict direct CP asymmetries in two-body charmless B decays. In this talk, I would like to report on a recent work on QCD Factorisation and Power Corrections in Charmless B Decays. Using the measured branching ratios for B → PV, it is shown that power corrections in charmless B decays are probably large, at least for penguin dominated PV channels. Since the tree-penguin interference resp… Show more
