Abstract: The LEP experiment limits the Standard Model (SM) Higgs to be heavier than the LEP reach of 114 GeV. Alternatively, the Higgs is light and was produced at LEP, but missed due to non-standard decays. I will discuss a "Hidden Higgs" scenario, where the Higgs decays dominantly into a light hidden sector, and back to the SM producing clusters of collimated leptons, known as "lepton jets." I will talk about the constraints from LEP and the Tevatron on this scenario and will conclude, surprisingly, that a light Higgs decaying to many leptons could have been missed at both experiments.
