چکیده

With a sample of approximately 89 x 10(6) B(-)B pairs collected with the BABAR detector, we perform a search for B meson decays into pairs of charmless vector mesons (phi, rho, and K*). We measure the branching fractions, determine the degree of longitudinal polarization, and search for CP violation asymmetries in the processes B+-->phiK(*+), B0-->phiK(*0), B+-->rho(0)K(*+), and B+-->rho(0)rho(+). We also set an upper limit on the branching fraction for the decay B0-->rho(0)rho(0).

Charmless non - leptonic B s decays to PP , PV and V V final states in the pQCD approach

Abstract We calculate the CP-averaged branching ratios and CP-violating asymmetries of a number of two-body charmless hadronic decays B0 s → PP,PV, V V in the perturbative QCD (pQCD) approach to leading order in αs (here P and V denote light pseudoscalar and vector mesons, respectively). The mixinginduced CP violation parameters are also calculated for these decays. We also predict the polariza...

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 two-body charmless B decays involving a tensor meson in ISGW2 model

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...

Reexamining charmless B → PV decays in QCD factorization approach

Using the QCD factorization approach, we reexamine the two-body hadronic charmless B-meson decays to final states involving a pseudoscalar (P ) and a vector (V ) meson, with inclusion of the important penguin contractions of the spectator-scattering amplitudes induced by the b → Dg∗g∗ (with D = d or s, and g∗ denoting an off-shell gluon) transition, which are of order αs. Their impacts on the C...
