Electroweak penguin B decays at Belle

Penguin-mediated B Decays at Belle

We report on the results of penguin-mediated B decays at the Belle experiment. The analyses were based on approximately 32 million BB events collected at the Υ(4S) resonance with the Belle detector at the KEKB ee storage ring. The b → sγ transition was studied through exclusive decays: B → K∗γ, B → K∗ 2 (1430) γ, B → Kππγ, B → Kπγ and B → Kργ. The b → sll transition was searched through both ex...

Effective 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...

The 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 ...
