The analyzed proton-proton collision data taken at a center-of-mass energy of sqrt(s) = 13 TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139/fb. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015-2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full dataset are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.91127.v2/t1","@type":"Dataset","description":"Distributions in SR-low of the data and post-fit background prediction for mT.
