CP-violating Higgs at Tevatron

Abstract

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 $p\bar{p}\text{ra}W{h}_2\text{ra}W{h}_1{h}_1\text{ra}l{\nu }_{l}b\bar{b}b\bar{b}$, with two or three tagged $b$ 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.
