The CP Asymmetry in $b \to s l^+ l^-$ Decay

Abstract

Using the experimental upper bound on the neutron EDM and experimental result on $b\rightarrow sγ$ branching ratio we have calculated CP asymmetry and $Γ^{2HDM}(b\rightarrow s{\it{l^{+}l^{-}}})/Γ^{SM}(b\rightarrow s{\it{l^{+}l^{-}}})$. It is shown that in the invariant dilepton mass $q^{2}$ region $(m_{ψ&#39;}^{2}+0.2\; GeV^{2})<\;q^{2}<\;m^{2}_{b}$ the CP asymmetry is maximal and quite detectable.
