CP-violating Higgs at Tevatron

We analyze the prospect for observing the intermediate neutral Higgs (h2) boson in its decay to two lighter Higgs bosons (h1) at the Tevatron in the framework of the CP violating MSSM using the PYTHIA event generator. We consider the lepton+4‐jets+E/T channel from pp→Wh2→Wh1h1→lvlbbbb, 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.
