In this paper, we investigate the effects of fourth generation quarks in the unpolarizedand polarized forward-backward asymmetries of decay. The fourth generation quarkschange the values of Wilson coefficients in effective Hamiltonian which is the main partof differential decay rate. Taking the with phase , we conclude that the forward-backward asymmetries of decay is very sensitive to existing of new parameters of fourthgeneration quarks for both leptons. In the end, It seems that the study of the forward-backward asymmetries can be a very useful tool for establishing new physics beyondStandard model as well as B-physics experiments.
