Resumo: | 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 bντˉb¯ντ and tντˉt¯ντ 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 bντˉb¯ντ channel, and 200 <mLQ3< 640 GeV in the tντˉt¯ντ channel. |
