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