CMS event displays : Highest Transverse Mass of the lepton-neutrino system

Collision events recorded by the CMS experiment in 2017, with a balanced high energy electron (or muon) and missing transverse momentum (MET). For the electron channel, the event has the largest transverse mass of 3.1 TeV after the signal selection criteria are applied. The electron energy deposit, shown in the green bars, has a transverse momentum of 1.57 TeV. The MET is 1.55 TeV, denoted by the purple line. For the muon channel, the event has the largest transverse mass of 2.9 TeV after the signal selection criteria are applied. The muon, shown as a red line, has a transverse momentum of 1.49 TeV. The MET is 1.50 TeV.
