CP-violating Higgs at Tevatron

We analyze the prospect for observing the intermediate neutral Higgs ($h_2$) boson in its decay to two lighter Higgs bosons ($h_1$) at the Tevatron in the framework of the CP violating MSSM using the PYTHIA event generator. We consider the lepton+ 4-jets+ $\text{met}$ channel from $p \bar p \ra W h_2 \ra W h_1 h_1 \ra l \nu_l b \bar b b\bar b$,withtwoorthreetagged$b$ jets. We found that it is very hard to observe this signature in the LEP-allowed region of parameter space, due to the small signal efficiency.
