Implementation Of The Cms-Exo-19-002 Search In The Madanalysis 5 Framework (Physics Beyond The Standard Model With Multilepton Final States; 137 Fb(-1))

In this paper, we present the MADANALYSIS 5 implementation of the CMS-EXO-19-002 analysis, probing an excess of events featuring multiple charged leptons in LHC proton-proton collisions at root s = 13TeV. The original analysis is based on data acquired by the CMS detector during the 2016-2018 campaign, which corresponds to an integrated luminosity of 137 fb(-1). Data have been tested against hypothetical extensions of the Standard Model where additional leptons can stem from new heavy fermion decays or from new light scalar/pseudoscalar decays. The CMS selection has been fully implemented in the MADANALYSIS 5 platform and successfully validated by reproducing official results in the form of signal distributions at the end of the selection.
