Abstract
Searches for pair-produced scalar leptoquarks are performed using 20 fb(-1) of proton-proton collision data provided by the LHC and recorded by the ATLAS detector at root s = 8 TeV. Events with two electrons (muons) and two or more jets in the final state are used to search for first (second)-generation leptoquarks. The results from two previously published ATLAS analyses are interpreted in terms of third-generation leptoquarks decaying to b nu(tau)(b) over bar(nu) over bar (tau) and t nu(tau)(t) over bar(nu) over bar (tau) final states. No statistically significant excess above the Standard Model expectation is observed in any channel and scalar leptoquarks are excluded at 95 % CL with masses up to m(LQ1) < 1050 GeV for first-generation leptoquarks, m(LQ2) < 1000 GeV for second-generation leptoquarks, m(LQ3) 625 GeV for third-generation leptoquarks in the b nu(tau)<(b) over bar(nu) over bar (tau) channel, and 200 < m(LQ3) < 640 GeV in the t nu(tau)(t) over bar(nu) over bar (tau) channel.
