چکیده

We search for B meson decays into two-body combinations of eta, eta', omega, and phi mesons from 89 x 10(6) BB pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We find the branching fraction B(B0-->etaomega)=(4.0(+1.3)(-1.2)+/-0.4)x10(-6) with a significance of 4.3 sigma. For the other decay modes we set the following 90% confidence level upper limits on the branching fractions, in units of 10(-6): B(B0-->etaeta)<2.8, B(B0-->etaeta')<4.6, B(B0-->eta'eta')<10, B(B0-->eta'omega)<2.8, B(B0-->etaphi)<1.0, B(B0-->eta'phi)<4.5, and B(B0-->phiphi)<1.5.

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...

Also examined are branching-fraction measurements or limits for the B0 s → D (∗) s D (∗) s modes (Belle, CDF, and DZero), the B0 s → γ γ radiative penguin decay (Belle), and three two-body charmless B0 s meson decay channels (CDF). Implications for the phenomenology of electroweak and QCD physics, as well as searches for physics beyond the Standard Model, are identified whe...

Charmless Hadronic B Decays at BABAR

We present several searches for charmless hadronic two-body and three-body decays of B mesons from electron-positron annihilation data collected by the BABAR detector near the Υ (4S) resonance. We report the preliminary branching fractions B(B → ππ) = (4.1± 1.0± 0.7)× 10, B(B → Kπ) = (16.7 ± 1.6 ± 1.3) × 10, B(B → ρπ) = (49 ± 13 −5) × 10, B(B → ηK) = (62± 18± 8)× 10, and present upper limits fo...

Updated Analysis of Some Two-body Charmless B Decays

New data from the BaBar, Belle, and CLEO Collaborations on B decays to two-body charmless final states are analyzed, with the following consequences: (1) The penguin amplitude which dominates the decay B+ → π+K∗0 has a magnitude similar to that dominating B+ → π+K0. (2) The decay B+ → π+η, a good candidate for observing direct CP violation, should be detectable at present levels of sensitivity....

Search for Charmless Hadronic Decays of B Mesons with the SLD Detector

Based on a sample of approximately 500,000 hadronic Z 0 decays accumulated between 1993 and 1998, the SLD experiment has set limits on 24 fully charged two-body and quasi two-body exclusive charmless hadronic decays of B + , B 0 , and B 0 s mesons. The precise tracking capabilities of the SLD detector provided for the efficient reduction of combinatoric backgrounds, yielding the most precise av...
