- Abstract
If the fourth generation fermions exist, the new quarks could influence the branching ratios of the decays of B→X[sub s]γ and B→X[sub s]l[sup +]l[sup -]. We obtain two solutions of the fourth generation CKM factor (formula available within PDF) from the decay of B→ X[sub s]γ. We use these two solutions to calculate the new contributions of the fourth generation quark to Wilson coefficients of the decay of B→ X[sub s]l[sup +]l[sup -]. The branching ratio and the forward–backward asymmetry of the decay of B→ X[sub s]l[sup +]l[sup -] in the two cases are calculated. Our results are quite different from that of SM in one case, almost the same in another case. If Nature chooses the former, the B meson decays could provide a possible test of the fourth generation existence.
