Abstract
In this paper, we investigate the effects of the fourth generation of quarks on the double-lepton polarization asymmetries in the decay. It is shown that these asymmetries in decay compared with those of decay are more sensitive to the fourth-generation parameters. We conclude that an efficient way to establish the existence of the fourth generation of quarks could be the study of these asymmetries in the decay.
