Penguin Mediated B Decays at B
We report on preliminary results of searches for penguin mediated B decays based on 20.7 fb −1 of data collected at the Υ (4S) peak with the BABAR detector at PEP-II. The following branching fractions have been measured: B(B + → φK +) = (7.7 −5.6 ± 1.7) × 10 −6 , where the first error is statistical and the second systematic. For several other modes we report upper limits on their branching fra...
متن کاملEffective Hamiltonian of Electroweak Penguin for Hadronic b Quark Decays
In this research we work with the effective Hamiltonian and the quark model. We investigate the decay rates of matter-antimatter of quark. We describe the effective Hamiltonian theory and apply this theory to the calculation of current-current ( ), QCD penguin ( ), magnetic dipole ( ) and electroweak penguin ( ) decay rates. The gluonic penguin structure of hadronic decays is studied thro...
متن کاملCharming-penguin Enhanced B Decays
Long-distance contributions of operators of the effective non-leptonic weak Hamiltonian containing charmed currents have been recently studied. Penguin-like contractions of these operators, denoted as charming penguins, have been shown to be relevant for several B decays into two pseudoscalar mesons. In particular, they are expected to give large enhancements to processes which would be otherwi...
متن کاملThe role of electroweak penguin and magnetic dipole QCD penguin on hadronic b Quark Decays
This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...
متن کاملRadiative Penguin Decays at the B Factories
In this article, I review the most recent results in radiative penguin decays from the B factories Belle and BABAR. Most notably, I will talk about the recent new observations in the decays B → (ρ/ω) γ, a new analysis technique in b → sγ, and first measurements of radiative penguin decays in the B s meson system. Finally, I will summarize the current status and future prospects of radiative pen...
