Implementation of the ATLAS-SUSY-2018-06 Analysis in the MadAnalysis 5 Framework (electroweakinos with Jigsaw Variables; 139 Fb−1)

We present the MadAnalysis 5 implementation and validation of the ATLAS-SUSY-2018-06 analysis. This analysis documents a search for electroweakinos with mass splittings larger than the [Formula: see text] boson mass. The targeted decay chain consists of electroweakinos decaying via on-shell [Formula: see text] and [Formula: see text] bosons to a three-lepton final state. The results are based on a dataset of 139 fb[Formula: see text] of proton-proton collisions, recorded by the ATLAS experiment with a center-of-mass energy of [Formula: see text] TeV between 2015 and 2018. The validation of our implementation relies on a comparison of our results against official cutflows provided by the ATLAS collaboration. The validation material provided by the ATLAS collaboration is based on well-defined benchmarks which feature chargino and neutralino associated production.
