A search for dijet resonances in events with at least one isolated charged lepon is performed using 139 fb^{−1} −1 of sqrt{s} s = 13 TeV proton-proton collision data recorded by the ATLAS detector at the LHC. The dijet invariant-mass (m_{jj} jj ) distribution constructed from events with at least one isolated electron or muon is searched in the region 0.22 < m_{jj} jj ​ < 6.3 TeV for excesses above a smoothly falling background from Standard Model processes. Triggering based on the presence of a lepton in the event reduces limitations imposed by minimum transverse momentum thresholds for triggering on jets. This approach allows smaller dijet invariant masses to be probed than in inclusive dijet searches, targeting a variety of new-physics models, for example ones in which a new state is produced in association with a leptonically decaying W or Z boson.
