Description
We will discuss different constraints on higgs decays into
dark sector and show that for light dark sector leading to cascade
decays of higgs the mass of the higgs is actually substantially lower
than SM limits at LEP. Through kinetic mixing the light dark sector at
the last stage decays back to visible sector, producing an interesting
novel signature of higgs decaying to lepton jets. After identifying
the relevant collider observables that characterize this scenario, and
study a wide range of LEP and Tevatron searches to recover the viable
regions in the space of observables, we find that the Higgs decaying
to lepton jets can be hidden when the event topology mimics that of
hadronic backgrounds. Thus, as many as 10^4 leptonic Higgs and SUSY
decays may be hiding in the LEP and Tevatron data. We present
benchmark models with a 100 GeV Higgs that are consistent with all
available collider constraints and dicsuss strategies for dedicated
searches at LEP, the Tevatron and the LHC.
