2 00 4 Lepton Polarization Asymmetry in B → l + l − decay Beyond the Standard Model

The lepton polarization asymmetry in the B → ℓ + ℓ − decay, when one of the leptons is polarized, is investigated using the most general form of the effective Hamiltonian. The sensitivity of the asymmetry to the new Wilson coefficients is studied.Moreover, correlations between the lepton polarization asymmetry and the branching ratio is studied. It is observed that, there are not exist such reg...

Double–lepton polarization asymmetries in the Exclusive B → ρl+l− decay beyond the Standard Model

The double–lepton polarization asymmetries in B → ρl+l− decay is analyzed in a model independent framework. The general expressions for nine double–polarization asymmetries are calculated. It is shown that the study of the double–lepton polarization asymmetries proves to be very useful tool in looking for new physics beyond the standard model.

Double–lepton polarization asymmetries in the B → Kl+l− decay beyond the Standard Model

General expressions for the double–lepton polarizations in the B → Kl+l− decay are obtained, using model independent effective Hamiltonian, including all possible interactions. Correlations between the averaged double–lepton polarization asymmetries and the branching ratio, as well as, the averaged single–lepton polarization asymmetry are studied. It is observed that, study of the double–lepton...

lν̄ decay and lepton polarization asymmetry

The lepton polarization asymmetry is studied for Bc → ηlν̄ decay. We have found that longitudinal, transversal and normal components of lepton polarizations can be measured for both μ and τ decay modes. PACS numbers 14.40, Nd 13.20, He 13.60-r, 11.30.Er ∗[email protected]

Lepton Polarization Asymmetry in B → K

We investigate the longitudinal lepton polarization asymmetry in the exclusive processes B → Kℓ + ℓ − and B → K * ℓ + ℓ −. We include both short and long-distance contributions to the asymmetry in our discussions. We find that average values of the polarization asymmetries of the muon and tau for B → K
