Polarized lepton pair forward–backward asymmetries in B → K∗l+l− decay beyond the standard model

We study the polarized lepton pair forward–backward asymmetries inB → K∗l+l− decay using the most general, model independent form of the effective Hamiltonian. We present the general expression for nine double–polarization forward–backward asymmetries. It is shown that, the study of the forward–backward asymmetries of the doubly–polarized lepton pair is a very useful tool for establishing new p...

2 00 5 Exclusive B → ρ l + l − decay and Polarized lepton pair forward – backward asymmetries

The polarized lepton pair forward–backward asymmetries in B → ρl+l− decay using a general, model independent form of the effective Hamiltonian is studied. The general expression for nine double–polarization forward–backward asymmetries are calculated. The study of the forward–backward asymmetries of the doubly–polarized lepton pair proves to be very useful tool in looking for new physics beyond...

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...

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.
