Search for new phenomena in multi-body invariant masses in events with at least one isolated lepton and two jets using √s = 13 TeV proton–proton collision data collected by the ATLAS detector ATLAS Collaboration
Abstract
A search for resonances in events with at least one isolated lepton (e or µ) and two jets is performed using 139 fb−1 of √ s = 13 TeV proton–proton collision data recorded by the ATLAS detector at the LHC. Deviations from a smoothly falling background hypothesis are tested in three- and four-body invariant mass distributions constructed from leptons and jets, including jets identified as originating from bottom quarks. Model-independent limits on generic resonances characterised by cascade decays of particles leading to multiple jets and leptons in the final state are presented. The limits are calculated using Gaussian shapes with different widths for the invariant masses. The multi-body invariant masses are also used to set 95% confidence level upper limits on the cross-section times branching ratios for the production and subsequent decay of resonances predicted by several new physics scenarios.

A search for resonances in events with at least one isolated lepton (e or µ) and
two jets is performed using 139 fb−1
of √
s = 13 TeV proton–proton collision data recorded
by the ATLAS detector at the LHC. Deviations from a smoothly falling background hypothesis are tested in three- and four-body invariant mass distributions constructed from leptons
and jets, including jets identified as originating from bottom quarks. Model-independent
limits on generic resonances characterised by cascade decays of particles leading to multiple
jets and leptons in the final state are presented. The limits are calculated using Gaussian
shapes with different widths for the invariant masses. The multi-body invariant masses
are also used to set 95% confidence level upper limits on the cross-section times branching
ratios for the production and subsequent decay of resonances predicted by several new
physics scenarios.
