Neutral Higgs boson contributions to CP asymmetry of $B \to ΦK_S$ in MSSM
We have studied the neutral Higgs boson (NHB) contributions to the pure penguin process $B\to ϕK_S$ in MSSM with middle and large $\tanβ$ (say, $>$ 8). We show that the $α_s$ order hadronic matrix elements of NHB induced operators can make sizable effects on both the branch ratio and time dependent CP asymmetry $S_{ϕK}$. Under the all relevant experimental constraints, the Higgs mediated contributions to $S_{ϕK}$ alone can provide a significant deviation from SM and, in particular, lead to a negative $S_{ϕK}$ which is reported by BaBar and Belle.
