Search for a Standard Model Higgs boson decaying to tau pairs and produced in association with a W or a Z boson at CMS

A search for the Standard Model H boson decaying to a tau pair and produced in association with a W or Z boson is presented using data collected in 2011 and 2012 with the CMS detector at the LHC. The topologies studied represent three- or four-charged lepton final states, where the SM H boson is produced in association with the leptonic decay of a W or Z boson, respectively. The analyses use CMS collision data samples corresponding to integrated luminosities of 4.9/fb collected at a centre-of-mass energy of 7 TeV and 19.7/fb of 8 TeV. No significant excess above the expected background is observed, resulting in exclusion limits between 0.96 and 8.9 times the Standard Model expectation for the product of Standard Model H cross section and tau pair decay branching fraction for H masses between 90 and 145 GeV.
