A Possibility of Large Electro-weak Penguin Contribution in B → Kπ Modes
We discuss about a possibility of large electro-weak penguin contribution in B → Kπ from recent experimental data. The several relations among the branching ratios which realize when the contributions from tree type and electro-weak penguin are small compared with the gluon penguin and can be treated as the expansion parameters do not satisfy the data. The difference comes from the r terms whic...

متن کاملLarge electroweak penguin contribution in B → Kπ and ππ decay modes
We discuss about a possibility of large electroweak penguin contribution in B → Kπ and ππ from recent experimental data. The experimental data may be suggesting that there are some discrepancies between the data and theoretical estimation in the branching ratios of them. In B → Kπ decays, to explain it, a large electroweak penguin contribution and large strong phase differences seem to be neede...
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 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 ...
