Anatomy of Prominent B and K Decays and Signatures of CP-Violating New Physics in the Electroweak Penguin Sector
The recent observation of Bd → π0π0 at the B factories with a surprisingly large branching ratio represents a challenge for theory, and complements the amazingly small Bd → π+π− rate. We point out that all puzzling B → ππ features can be accommodated in the Standard Model (SM) through non-factorizable hadronic interference effects, extract the relevant parameters, and predict the CP asymmetries...
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 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 کاملSearch for New Physics in CP -violating B Decays
We consider three possible scenarios of new physics in B0 d-B̄ 0 d mixing and propose a simple framework for analyzing their effects. This framework allows us to study the CP asymmetry in semileptonic Bd decays (ASL) and those in nonleptonic transitions such as Bd → J/ψKS and Bd → π +π−. Numerically we find that new physics may enhance the magnitude of ASL up to the percent level within the appr...
متن کاملNew Physics Effects in Cp-violating B Decays
Contributions to B − ¯ B mixing from physics beyond the standard model may be detected from CP-violating asymmetries in B decays. There exists the possibility of large new contributions that cannot be detected by first generation experiments because of a discrete ambiguity. Some possible strategies for resolving this are discussed. A major goal of the experiments on B mesons is to check the sta...
