11 Jun 2003 | Journal: | Phys.Lett. B585 (2004) 287-294 | Subject: | hep-ph | Abstract: | We have studied the neutral Higgs boson (NHB) contributions to the pure penguin process $B o phi K_S$ in MSSM with middle and large $ aneta$ (say, $>$ 8). We show that the $alpha_s$ order hadronic matrix elements of NHB induced operators can make sizable effects on both the branch ratio and time dependent CP asymmetry $S_{phi K}$. Under the all relevant experimental constraints, the Higgs mediated contributions to $S_{phi K}$ alone can provide a significant deviation from SM and, in particular, lead to a negative $S_{phi K}$ which is reported by BaBar and Belle. | Source: | arXiv, hep-ph/0306086 | Services: | Forum | Review | PDF | Favorites |
