Title

CP violation, single lepton polarization asymmetry, and polarized CP asymmetry in B→K*ℓ+ℓ- decay in the four-generation standard model

English Abstract

In this paper we present a study of CP asymmetry, single lepton polarization asymmetry and polarized CP asymmetry in B→K*ℓ+ℓ- decay within the four-generation standard model. Taking |Vt′s*Vt′b|=0.01, 0.02, 0.03 with phase {60°–120°}, which is consistent with the b→sℓ+ℓ- rate and the Bs mixing parameter ΔmBs, we find that CP asymmetry, single lepton polarization asymmetry and polarized CP asymmetry are sensitive to the existence of the fourth generation. This can serve as an indirect method to search for new physics effects, in particular, to search for the fourth-generation quarks(t′,b′) via their indirect manifestations in loop diagrams.
