| dc.description | We investigate the mass differences $ΔM_{B_{d,s}}$ in the mixing $B^0_{d,s}-\bar B^0_{d,s}$ with a new up-like quark $t^{\prime}$ in the sequential fourth generation model. We give the basic formulae for $ΔM_{B_{d,s}}$ in this model and obtain two kinds of numerical results of $ΔM_{B_{s}}$ which is the function of $m_{t^{\prime}}$. We find that one of our results can satisfy the present experimental low bound of $ΔM_{B_s}$. We also get the constraints of the fourth generation CKM factor $V^{*}_{t^{'}b}V_{t^{'}d}$, which is the function of $t^{'}$, from the experimental measurements of $ΔM_{B_d}$. Thus, $ΔM_{B_{d,s}}$ provide a possible test of the fourth generation and give a signal of the new physics. | |
