Search for high-mass resonances decaying into τ-lepton pairs in pp collisions at √s = 7 TeV
A search for high-mass resonances decaying into τ[superscript +]τ[superscript −] is performed using a data sample of pp collisions at √s = 7 TeV. The data were collected with the CMS detector at the LHC and correspond to an integrated luminosity of 4.9 fb[superscript −1]. The number of observed even...

| description | A search for high-mass resonances decaying into τ[superscript +]τ[superscript −] is performed using a data sample of pp collisions at √s = 7 TeV. The data were collected with the CMS detector at the LHC and correspond to an integrated luminosity of 4.9 fb[superscript −1]. The number of observed events is in agreement with the standard model prediction. An upper limit on the product of the resonance cross section and branching fraction into τ-lepton pairs is calculated as a function of the resonance mass. Using the sequential standard model resonance Z′[subscript SSM] and the superstring-inspired E[subscript 6] model with resonance Z′[subscript ψ] as benchmarks, resonances with standard model couplings with masses below 1.4 and 1.1 TeV, respectively, are excluded at 95% confidence level. |
