| Abstract: | General expressions for the double-lepton polarizations in the  decay are obtained, using a 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 a study of the double-lepton polarization asymmetries can serve as a good test for establishing new physics beyond the standard model.Received: 23 November 2003, Revised: 8 March 2004, Published online: 30 April 2004 |
