Search for resonant lepton+jet production with the ATLAS experiment — •Jiyoung Kim, Adrian Fernandez, and Stefan Tapprogge — Institute for Physics, Johannes Gutenberg University, Mainz
The leptoquark (LQ) is a hypothetical particle, which carries both lepton and quark quantum numbers. Its existence could point to extended theories beyond the Standard Model. If such particles were to exist, their decays might be observable in high-energy pp collisions using the ATLAS detector at the LHC. In this contribution, the specific interest is single LQ production leading to a resonant structure in the lepton-jet invariant mass. The search strategy about the existence of the LQs will be presented, including optimization of the selection cuts and comparison with the run 2 data set from ATLAS (with an integrated luminosity of 139 fb−1 at √s=13 TeV).
