This study investigates the influence of the fourth generation
quarks on the double lepton polarizations in B \rar K l+l− decay. Taking |Vt′sVt′b| ∼ {0.01−0.03} with
phase about 100°, which is consistent with the b→sl+l− rate and the Bs mixing parameter ∆mBs, we obtain that the double lepton(μ, τ)
polarizations are quite sensitive to the existence of fourth
generation. It can serve as a good tool to search for new physics
effects, precisely, to indirect search for the fourth generation
quarks(t′, b′).
