Searches for new phenomena in events with two leptons, jets, and missing transverse momentum in 139 fb−1 of √s = 13 TeV pp collisions with the ATLAS detector ATLAS Collaboration
Abstract
Searches for new phenomena inspired by supersymmetry in final states containing an e+e− or μ+μ− pair, jets, and missing transverse momentum are presented. These searches make use of proton–proton collision data with an integrated luminosity of 139 fb−1, collected during 2015– 2018 at a centre-of-mass energy √s = 13 TeV by the ATLAS detector at the Large Hadron Collider. Two searches target the pair production of charginos and neutralinos. One uses the recursive-jigsaw reconstruction technique to follow up on excesses observed in 36.1 fb−1 of data, and the other uses conventional event variables. The third search targets pair production of coloured supersymmetric particles (squarks or gluinos) decaying through the next-to-lightest neutralino (χ˜ 0 2 ) via a slepton ( )˜ or Z boson into + −χ˜ 0 1 , resulting in a kinematic endpoint or peak in the dilepton invariant mass spectrum. The data are found to be consistent with the Standard Model expectations. Results are interpreted using simplified models and exclude masses up to 900 GeV for electroweakinos, 1550 GeV for squarks, and 2250 GeV for gluinos.

Description |
Searches for new phenomena inspired by supersymmetry in final states containing an e+e− or μ+μ− pair,
jets, and missing transverse momentum are presented. These
searches make use of proton–proton collision data with an
integrated luminosity of 139 fb−1, collected during 2015–
2018 at a centre-of-mass energy √s = 13 TeV by the ATLAS
detector at the Large Hadron Collider. Two searches target
the pair production of charginos and neutralinos. One uses
the recursive-jigsaw reconstruction technique to follow up
on excesses observed in 36.1 fb−1 of data, and the other uses
conventional event variables. The third search targets pair
production of coloured supersymmetric particles (squarks
or gluinos) decaying through the next-to-lightest neutralino
(χ˜ 0
2 ) via a slepton ( )˜ or Z boson into + −χ˜ 0
1 , resulting
in a kinematic endpoint or peak in the dilepton invariant
mass spectrum. The data are found to be consistent with the
Standard Model expectations. Results are interpreted using
simplified models and exclude masses up to 900 GeV for
electroweakinos, 1550 GeV for squarks, and 2250 GeV for
gluinos.
