چکیده انگلیسی
A search for high-mass resonances decaying into Ï+Ïâ 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 fbâ1. 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 Ï-lepton pairs is calculated as a function of the resonance mass. Using the sequential standard model resonance ZSSMâ² and the superstring-inspired E6 model with resonance ZÏâ² as benchmarks, resonances with standard model couplings with masses below 1.4 and 1.1 TeV, respectively, are excluded at 95% confidence level.
