Searches for scalar leptoquarks in pp collisions at √s = 8TeV 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 √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...

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 bν τ b̄ ν̄ τ and tν τ t̄ν̄ 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 mL Q1 < 1050 GeV for first-generation leptoquarks, mL Q2 < 1000 GeV for second-generation leptoquarks, mL Q3 < 625 GeV for third-generation leptoquarks in the bν τ b̄ ν̄ τ channel, and 200 < mL Q3 < 640 GeV in the tν τ t̄ν̄ τ channel. © CERN for the benefit of the ATLAS collaboration 2015.
