Search for high-mass dilepton resonances in 6.1/fb of pp collisions at sqrt(s)= 8 TeV with the ATLAS experiment

The ATLAS detector is used to search for heavy neutral gauge bosons (Z′) decaying to an electron-positron pair or a muon-antimuon pair. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 8 TeV corresponding to an integrated luminosity of approximately 5.9 (e+e...

description The ATLAS detector is used to search for heavy neutral gauge bosons (Z′) decaying to an electron-positron pair or a muon-antimuon pair. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 8 TeV corresponding to an integrated luminosity of approximately 5.9 (e+e-) / 6.1 (mu+mu-) fb^-1. A Z′ with standard model Z couplings to fermions is excluded at 95% CL for masses below 2.39 TeV in the electron channel, 2.19 TeV in the muon channel, and 2.49 TeV in the two channels combined. The result is also interpreted in a Grand Unification model based on the E6 gauge group.
