Search for pair-produced first and second generation scalar leptoquarks in pp collisions at √s = 13 TeV with the ATLAS detector at the LHC — Stefan Tapprogge and •Anton Wolf — Institut für Physik, Johannes Gutenberg-Universität Mainz
Leptoquarks (LQs) are predicted in many extensions of the Standard Model (SM) and may provide an explanation for many observed similarities between the quark and lepton sectors of the SM. LQs are commonly assumed to couple to quarks and leptons of the same generation.
The talk will summarize results of a search for pair-produced first and second generation LQs. Channels where both LQs decay to a charged lepton and a quark are considered. The probed final states consist of exactly two same flavour opposite sign leptons (electrons or muons) and at least two jets. The dataset used was recorded in 2015 and 2016 by the ATLAS experiment. It corresponds to 36.1 fb−1 of pp collision data at a center-of-mass energy of 13 TeV.
