Implementation of the ATLAS-EXOT-2018-030 analysis in the MADANALYSIS 5 framework (W ' boson into a lepton and a neutrino; 139 fb(-1))

Abstract

We present the MADANALYSIS 5 implementation of the heavily charged gauge boson search to recast the analysis of its decay into one charged lepton and missing transverse momentum. Signal events describing pp -> W '-> l nu(l) (l = e or mu) at root s = 13 TeV in the sequential standard model are generated by the MADGRAPH5_AMC@NLO at leading order. The corresponding signal cross-sections for both electron and muon channels vary from 195 fb to 0.238 fb depending on the pole mass of the W ' boson in the range of 2 TeV to 6 TeV. We validate our implementation by comparing the transverse mass distributions of our signal prediction to those of the ATLAS analysis for an integrated luminosity of 139 fb(-1).
