Searching for doubly-charged Higgs bosons at future colliders

Description: Doubly-charged Higgs bosons ({Delta}{sup --}/{Delta}{sup ++}) appear in several extensions to the Standard Model and can be relatively light. We review the theoretical motivation for these states and present a study of the discovery reach in future runs of the Fermilab Tevatron for pair-produced doubly-charged Higgs bosons decaying to like-sign lepton pairs. We also comment on the discovery potential at other future colliders. 16 refs., 3 figs., 1 tab.

Search for charged Higgs bosons in CDF

Description: We present results of a direct search for charged Higgs production from {ital p}{ital {anti p}} collisions at {radical}s = 1.8 TeV at Fermilab`s Tevatron collider using the CDF detector. An expanded Higgs sector containing charged Higgs bosons is a persistent feature of candidate theories to replace the Standard Model. The minimal supersymmetric extension of the Standard Model, for example predicts that the dominant decay mode of the top quark is {ital t} {r_arrow} H{sup +}{ital b} {r_arrow} {tau}{sup +} {ital vb} for large values of tan {Beta}. We use the hadronic decays of the tau lepton in this channel to exclude charged Higgs bosons with M{sub H{sup {+-}}} {lt} 140 GeV/c{sup 2} for large tan{Beta}.

Charged Higgs and SUSY searches at CDF

Description: We present recent results of supersymmetric (SUSY) particle searches at the Collider Detector at Fermilab. These include searches for squarks, gluinos, charginos, and neutralinos using the {ital E}{sub T}-multijet, like-sign dilepton, and trilepton SUSY signatures. Results from a charged Higgs search using the hadronic decays of the tau lepton are also presented.
