Abstract

A search for the standard model Higgs boson decaying to tau pairs is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012 at a center-of-mass energy of 7 and 8 TeV respectively. The dataset corresponds to an integrated luminosity of 17 fb ¹, split in 4.9 fb ¹ of data taken at 7 TeV center-of-mass energy and 12.1 fb¹ at 8 TeV. The tau-pair invariant-mass spectrum is studied in five different final states, μτ_h + X, eτ_h + X, eμ + X, τ_hτ_h + X, and μμ + X. Upper limits with respect to the standard model prediction in the mass range of 110-145 GeV are determined. An observed (expected) 95% confidence level exclusion limit for m_H = 125 GeV is found to be 1.63 (1.00) times the standard model cross section.
