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 ...
متن کاملElectroweak Corrections to the Top Quark Decay
We have calculated the one-loop electroweak corrections to the decay t→ bW, including the counterterm for the CKM matrix elements Vtb. Previous calculations used an incorrect δVtb that led to a gauge dependent amplitude. However, since the contribution stemming from δVtb is small, those calculations only underestimate the width by roughly one part in 10. PACS number(s): 12.15.Lk, 11.10.Gh, 12.1...
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 کاملTop Dipole Form Factors and Loop–induced CP violation in Supersymmetry
The one–loop Minimal Supersymmetric Standard Model (MSSM) contributions to the weak and electromagnetic dipole form factors of the top quark are presented. Far from the Z peak, they are not sufficient to account for all the new physics effects. In the context of the calculation of the process e+e− → tt̄ to one loop in the MSSM, we compare the impact on the phenomenology of the CP–violating dipol...
متن کاملDipole Form Factors and Loop–induced CP violation in Supersymmetry
The one–loop Minimal Supersymmetric Standard Model (MSSM) contributions to the weak and electromagnetic dipole form factors of heavy fermions are reviewed. For the Z boson on shell, the weak–magnetic and weak–electric dipole moments of the τ lepton and the b quark can be defined and directly connected to observables. But far from the Z peak, the weak and electromagnetic dipole form factors are ...
