Difference in B+ and B0 direct CP asymmetry as an effect of a fourth generation.
Direct CP violation in B0 --> K+ pi- decay has emerged at the -10% level, but the asymmetry in B+ --> K+ pi0 mode is consistent with zero. This difference points towards possible new physics in the electroweak penguin operator. We point out that a sequential fourth generation, with sizable V(t' s)* V(t' b) and near maximal phase, could be a natural cause. We use the perturbative QCD factorizati...
متن کاملMeasurement of CP-violating asymmetries in B0 decays to CP eigenstates.
We present measurements of time-dependent CP-violating asymmetries in neutral B decays to several CP eigenstates. The measurement uses a data sample of 23x10(6) Upsilon(4S)-->BbarB decays collected by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we find events in which one neutral B meson is fully reconstructed in a CP eigenstate containing charmonium and the f...
متن کاملCP asymmetries in B s decays and spontaneous CP violation
We study possible effects of new physics in CP asymmetries in two-body B s decays in left-right models with spontaneous CP violation. Considering the contributions of new CP phases to the B s mixing as well as to the penguin dominated decay amplitudes we show that, with the present constraints large deviations from the standard model predictions in CP asymmetries are allowed in both cases. Dete...
متن کاملRelations for Direct CP asymmetries in B → PP and B → PV decays 1
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...
