Abstract

In this paper we analyze the dilepton mass square q² dependency of single lepton polarization asymmetries and CP violation for B→ K₀^*(1430) ℓ⁺ℓ^-, ℓ=μ,τ) in the 2HDM context. Also, we study the averages of these asymmetries in the domain 4 m_ℓ²<q²< (m_B-m_K₀^*)². Our study manifests that the investigation of the above-mentioned asymmetries for B→ K₀^*(1430) ℓ⁺ℓ^- processes could provide useful information for probing new Higgs bosons in the future B-physics experiments.
