dc.description.abstract	A search for high-mass resonances decaying into τ +τ - is performed using a data sample of pp collisions at s=7TeV. The data were collected with the CMS detector at the LHC and correspond to an integrated luminosity of 4.9 fb -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 ZSSM' and the superstring-inspired E 6 model with resonance Zψ' as benchmarks, resonances with standard model couplings with masses below 1.4 and 1.1 TeV, respectively, are excluded at 95% confidence level. © 2012 CERN.
