In this paper, we investigate the effects of fourth generation quarks in the unpolarized
and polarized forward-backward asymmetries of decay. The fourth generation quarks
change the values of Wilson coefficients in effective Hamiltonian which is the main part
of 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 fourth
generation 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 beyond
Standard model as well as B-physics experiments.
