Findings

No evidence for charged Higgs production

Set limits on production cross-sections for various models

First search for doubly-charged Higgs decaying to tau leptons

Abstract

We present searches for charged Higgs production in decays of top quarks and also pair production of doubly charged Higgs boson decaying to di-tau, di-muon, and muon + tau final states. The searches are performed in proton-antiproton collisions at sqrt{s} = 1.96 TeV using an integrated luminosity of up to 7 fb-1 collected by the CDF and D0 experiments at the Fermilab Tevatron Collider. We find no evidence for charged Higgs production and set limits on the production cross-section for a variety of theoretical models. This represents the first search for pair production of doubly-charged Higgs bosons decaying into tau leptons at a hadron collider.
