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...
متن کاملB Decays and CP Violation
We review the status of the theory and phenomenology of heavy-quark symmetry, exclusive weak decays of B mesons, inclusive decay rates and lifetimes of b hadrons, and CP violation in B-meson decays.

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 کاملCP Violation in B Decays
In the near future, we will have the first significant experimental measurements of CP violation in B decays. These measurements will easily test crucial questions such as whether the Standard Model Kobayashi-Maskawa phase plays a dominant role in CP violation or whether CP is an approximate symmetry in nature. We explain the different types of CP violation in B decays, and the usefulness of me...
متن کاملImplications of Non-Standard CP Violation in Hadronic B-Decays
We investigate a class of models for new physics which could produce a large difference in sin 2β between B0 → J/ψKS and the “pure penguin” mode B0 → φKS . In such models, the dominant effect is through a Z-penguin and therefore a pattern of deviation in sin 2β as measured in B0 → χ1KS ; ηcKS ; J/ψKS and ψKS is predicted. If the preliminary data concerning the discrepancy between J/ψKS and φKS ...
