Searches for scalar leptoquarks in pp collisions at sqrt(s) = 8 TeV with the ATLAS detector

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 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 b?tb¯?t¯ and t?tt¯?t¯ 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 b?tb¯?t¯ channel, and 200 <mLQ3< 640 GeV in the t?tt¯?t¯ channel.
