A Search for Higgs Bosons in Final States with Multiple Tau Leptons at the D0~Experiment
- Manchester U.
Two searches for the production of Higgs bosons decaying into $$\tau$$ and $$\mu$$ leptons, using data collected with the D\O\ 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 $$q\bar{q} \to \Hpp\Hmm$$, where $$\Hpm$$ 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 $<$ $$M_{H^{\pm\pm}}$$ $<$ 200 GeV. A second search for the production of the Standard Model Higgs boson in the final state $$\tau\tau\mu+X$$ is presented, using an integrated luminosity of $L=8.6$ fb$$^{-1}$$. Again no significant excess of data is observed over the background expectation and $$95\%$$ C.L. limits are set on the observed cross section relative to the Standard Model prediction, in the range 100 $<$ $$M_{H}$$ $<$ 200 GeV.
