Higgs decaying to lepton jets

This event is part of the HET Seminar Series.

Abstract:
I will talk about a class of models where the Higgs boson can be much
lighter than the naive LEP limit of 114.4 GeV without violating any
experimental constraints. The loophole is that the Higgs searches at
LEP are less sensitive to Higgs decaying into multiparticle final
states. The most recent theoretical idea along this line is Higgs
decaying to a large number of collimated leptons, so-called lepton
jets. I will discuss the prospects to search for such a Higgs particle
at Tevatron and the LHC, as well as in the old LEP data.
