We search for the pair production of doubly charged Higgs particles followed by the lepton-flavor violating decay of each Higgs into electron-and-tau and muon-and-tau pairs using 350 pb{sup -1} of data collected by the CDF II experiment at the Fermilab Tevatron. Separate searches investigate cases where three or four final state leptons are detected, and the limits for each exclusive decay mode reflect the combined results of both searches. Assuming the H{sup {+-}{+-}}{sub L} decays exclusively into like sign electron-and-tau pairs, we set a lower limit on its mass of 114 GeV/c2 at the 95 % confidence level. In the case of exclusive muon-and-tau decays, we set a lower mass limit of 112 GeV/c2 also at the 95% confidence level.

The data collected at the TeVatron RunIIa have been used to look for supersymmetric charged Higgs boson and Left-Right suspersymmetric doubly charged Higgs boson. No signal of such bosons has been found and this note reports on the current analyses and their observed excluded domains in models parameter space.

Two searches for the production of Higgs bosons decaying into [tau] and [mu] leptons, using data collected with the DØ detector at the Fermilab Tevatron p$\bar{p}$ collider, are presented. A search for the pair production of doubly charged Higgs bosons in the process q$\bar{q}$ 2!H++H--, where H ±± decays to [tau][tau], [mu][mu] or [tau][mu] lepton pairs, with an integrated luminosity of up to L = 7:0 fb-1, is presented. No signi cant excess of data over the expected SM background is observed and the results are used to set 95% C.L. limits on the pair production cross section of doubly charged Higgs bosons in the range 90

Two searches for the production of Higgs bosons decaying into tau and mu leptons, using data collected with the DZero detector at the Fermilab Tevatron p-bar(p)collider, are presented. A search for the pair production of doubly charged Higgs bosons in the processq-bar(q) to H {++}H {--}, where H {++} decays to tau-tau, mu-mu or tau-mu lepton pairs, with an integrated luminosity of up to L= 7.0 fb {-1}, is presented. No significant excess of data over the expected SM background is observed and the results are used to set 95\% C.L. limits on the pair production cross section of doubly charged Higgs bosons in the range 90

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.

We summarize the status of Higgs boson searches at the upgraded Fermilab Tevatron performed by the D0 and CDF collaborations. We report on three categories of searches, namely the search for the Standard Model Higgs boson (p{bar p} {yields} H, WH or ZH, with H {yields} WW* and/or H {yields} b{bar b}), the search for the minimal supersymmetric Higgs boson using p{bar p} {yields} hb{bar b} {yields} b{bar b}b{bar b} and p{bar p} {yields} hX {yields} {tau}{tau}X, and the search for doubly charged Higgs boson.
