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

Searches for pair-produced scalar leptoquarks are performed using 20 fb<sup>-1</sup> 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 firs...

description Searches for pair-produced scalar leptoquarks are performed using 20 fb<sup>-1</sup> 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 bν<sub>τ</sub>b¯v¯<sub>τ</sub> and tν<sub>τ</sub>t¯v¯<sub>τ</sub> 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<sub>LQ1</sub> < 1050 GeV for first-generation leptoquarks, m<sub>LQ2</sub> < 1000 GeV for second-generation leptoquarks, m<sub>LQ3</sub> < 625 GeV for third-generation leptoquarks in the bν<sub>τ</sub>b¯v¯<sub>τ</sub> channel, and 200 < m<sub>LQ3</sub> < 640 GeV in the tν<sub>τ</sub>t¯v¯<sub>τ</sub> channel.
