Lepton polarization and CP-violating effects in $\overline{B}\to {\overline{K}}_0^{\ast }(1430){\ell }^{+}{\ell }^{-}$ Decay in Standard and Two Higgs Doublet Model

Abstract

In this paper we analyze the dilepton mass square $q^2$ dependency of single lepton polarization asymmetries and CP violation for $\overline{B}\to {\overline{K}}_0^{\ast }(1430){\ell }^{+}{\ell }^{-},\ell =\mu ,\tau )$ in the 2HDM context. Also, we study the averages of these asymmetries in the domain $4m_{\ell }^2<q^2<(m_B-m_{K_0^{\ast }}{)}^2$. Our study manifests that the investigation of the above-mentioned asymmetries for $\overline{B}\to {\overline{K}}_0^{\ast }(1430){\ell }^{+}{\ell }^{-}$ processes could provide useful information for probing new Higgs bosons in the future B-physics experiments.
