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 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 ...
متن کاملThe Anomalous Chromomagnetic Dipole Moment of the Top Quark in Different Frameworks
We give explicit formulae for the anomalous chromomagnetic dipole moment of the top quark in the framework of the standard model, the two higgs doublet model and the minimal supersymmetric standard model. Finally, we compare the results for this coupling with the bound −0.03 ≤ ∆κ ≤ 0.01 coming from analysis of b → sγ process whith an on-shell gluon. The top quark is the heaviest fermion in the ...
متن کاملTop Quark Mass and Supersymmetry
We summarize the expectations for the top quark mass in supersymmetric models and discuss the potential implications of its value measured by the CDF group in Fermilab.
