Higgs boson searches with tau leptons in CMS.

Taus, being the heaviest of the leptons, constitute an important tool for searches for new physics at the LHC. Higgs boson couples to mass leading to a significant branching ratio of about 10% for low mass Higgs decaying to tau pairs. Taus become even more important in the minimal supersymmetric extension of the Standard model where the neutral Higgs production is enhanced and the presence of two Higgs doublets results in prediction of additional charged Higgs bosons that may preferentially decay to final states with tau leptons. This paper describes a search for Higgs bosons decaying to di-tau pairs and a search for charged Higgs bosons decaying to taus and neutrinos using about 1 fb-1 of data collected with the CMS detector in 2011.
