CP asymmetry in B decay induced by a light Higgs

A light Higgs provides a useful tool to observe CP asymmetry through its copious productins in B0 decays. The estimated luminosity needed to detect the asymmetry in Bd→HKS, e.g., is within the reach of proposed B factory experiments at least for larger top quark masses. It also pointed out that the sign and/or magnitudes of CP asymmetries in various B0 decays into the Higgs are quite different from what we expect for the well discussed corresponding decays due to gauge interactions, such as Bd→ψKS.
