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 √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 bντ b̄ ν̄τ and tντ t̄ν̄τ 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 mLQ1 < 1050 GeV for first-generation leptoquarks, mLQ2 < 1000 GeV for second-generation leptoquarks, mLQ3 < 625 GeV for third-generation leptoquarks in the bντ b̄ ν̄τ channel, and 200 < mLQ3 < 640 GeV in the tντt̄ν̄τ channel.
