Title: Searches for scalar leptoquarks in pp collisions at $$\sqrt{s}$$ = 8 TeV with the ATLAS detector

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 $$\sqrt{s}$$ = 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 $$bν_τ\bar{b}\bar{ν}_τ$$ and $$tν_τ\bar{t}\bar{ν}_τ$$ 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 $$bν_τ\bar{b}\bar{ν}_τ$$ channel, and 200 < mLQ3 < 640 GeV in the $$tν_τ\bar{t}\bar{ν}_τ$$ channel.
