    Abstract

    Searches for pair-produced scalar leptoquarks are performed using 20 fb$$^{-1}$$-1 of proton–proton collision data provided by the LHC and recorded by the ATLAS detector at $$\sqrt{s}=8$$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 $$b\nu _{\tau }\bar{b}\bar{\nu _{\tau }}$$bντb¯ντ¯ and $$t\nu _{\tau }\bar{t}\bar{\nu _{\tau }}$$tντt¯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 $$m_{\mathrm {LQ1}}
