A search for high-mass resonances decaying to ?+? in pp collisions at s = 8 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search for high-mass resonances decaying into ?+ ? final states using proton-proton collisions at s=8 TeV produced by the Large Hadron Collider is presented. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 19.5?20.3 fb1. No statistically significant excess above the Standard Model expectation is observed, 95% credibility upper limits are set on the cross section times branching fraction of Z resonances decaying into ?+ ? pairs as a function of the resonancemass. As a result, Z bosons of the Sequential Standard Model with masses less than 2.02 TeV are excluded at 95% credibility. The impact of the fermionic couplings on the Z acceptance is investigated and limits are also placed on a Z model that exhibitsenhanced couplings to third-generation fermions.
