Search for the SM Higgs Boson in Di-[tau] Final States at CMS

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 super(1), split in 4.9 fb super(1) of data taken at 7 TeV center-of-mass energy and 12.1 fb super(1) at 8 TeV. The tau-pair invariant-mass spectrum is studied in five different final states, mu [tau] sub(h) + X, e[tau] sub(h), + X, e mu + X, [tau] sub(h)[tau] sub(h), + X, and mu mu + 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 sub(H) = 125 GeV is found to be 1.63 (1.00) times the standard model cross section.
