Searching for leptoquarks with the ATLAS detector

Abstract

Results from the latest searches for pair-produced scalar leptoquarks using 36.1 ${\text{fb}}^{-1}$ of $pp$-collision data recorded by the ATLAS detector at $\sqrt{s}$ = 13 TeV were presented. No statistically significant excess of data over Standard Model prediction is observed. The observed limits on first- (second-) generation leptoquark masses are excluded up to 1400 (1560) GeV in the minimal Buchmüller-Rückl-Wyler model, assuming a leptoquark decay branching ratio of 100% into a charged lepton and a quark. Third generation leptoquark masses are excluded up to 1000 GeV at the highest and lowest decay branching ratios for both up-type and down-type leptoquarks.
