Finding the Light, Hidden Higgs

Precision electroweak constraints favor a Higgs with a mass near 100 GeV, but searches at LEP and the Tevatron have so far found no evidence for it. It is possible that the Higgs is lighter than the LEP bound of 114 GeV for the Standard Model Higgs because non-standard decays or couplings have prevented it from appearing in standard searches. This workshop will explore the prospects for detecting such a “hidden” Higgs. Topics include decays to 4 b, 4 tau, missing energy + X, multijets, and also suppressed Higgs production.
