Abstract

Two searches for the production of Higgs bosons decaying into tau and mu leptons, using data collected withthe 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 significantexcess of data over the expected SM background is observed and the results are usedto set 95\% C.L. limits on the pair production cross section of doubly charged Higgs bosons in the range 90 <M_{H^{++}} <200 GeV. A second search for the production of theStandard Model Higgs boson in the finalstate tau-tau-mu+X is presented, using an integratedluminosity of L=8.6 fb^{-1}. Again no significantexcess of data is observed over the backgroundexpectation and 95% C.L. limits are set on the observed cross sectionrelative to the Standard Model prediction, in the range 100 <M_{H} <200 GeV.
