Measurement of charge asymmetries in charmless hadronic B meson decays.

چکیده
We search for CP-violating charge asymmetries (alpha(CP)) in the B meson decays to K(+/-)pi(-/+), K(+/-)pi(0), K(0)(S)pi(+/-), K(+/-)eta('), and omega pi(+/-). Using 9.66 million upsilon(4S) decays collected with the CLEO detector, the statistical precision on alpha(CP) is in the range of +/-0.12 to +/-0.25 depending on decay mode. While CP-violating asymmetries of up to +/-0.5 are possible within the standard model, the measured asymmetries are consistent with zero in all five decay modes studied.

Hadronic B Decays to Charmless V T Final States
Charmless hadronic decays of B mesons to a vector meson (V ) and a tensor meson (T ) are analyzed in the frameworks of both flavor SU(3) symmetry and generalized factorization. We also make comments on B decays to two tensor mesons in the final states. Certain ways to test validity of the generalized factorization are proposed, using B → V T decays. We calculate the branching ratios and CP asym...

Nonleptonic charmless B decays into a pseudoscalar (P ) or a vector (V ) meson accompanying a tensor (T ) meson are re-analyzed. We scrutinize the hadronic uncertainties and ambiguities of the form factors which appear in the literature. The Isgur-Scora-Grinstein-Wise updated model (ISGW2) is adopted to evaluate the relevant hadronic matrix elements. We calculate the branching ratios and CP asy...
متن کاملQCD factorization and CP asymmetries in hadronic B decays
We review recent advances in the theory of strong-interaction effects and final-state interactions in hadronic weak decays of heavy mesons. In the heavy-quark limit, the amplitudes for most nonleptonic, two-body B decays can be calculated from first principles and expressed in terms of semileptonic form factors and lightcone distribution amplitudes. We summarize the main features of this novel ...

متن کاملExclusive charmless Bs hadronic decays into η ′ and η
Exclusive charmless B s hadronic decays into η ′ and η Using the next-to-leading order QCD-corrected effective Hamiltonian, charmless exclusive nonleptonic decays of the Bs meson into η or η ′ are calculated within the generalized factorization approach. Nonfactorizable contributions are included with two different treatments. Some subtleties involved are discussed.
