Descripción
A search for a heavy neutral lepton N of Majorana nature decaying into a
W boson and a charged lepton is performed using the CMS detector at the
LHC. The targeted signature consists of three prompt charged leptons in
any flavor combination of electrons and muons. The data were collected
in proton-proton collisions at a center-of-mass energy of 13 TeV, with
an integrated luminosity of 35.9 fb-1 . The search is
performed in the N mass range between 1 GeV and 1.2 TeV. The data are
found to be consistent with the expected standard model background.
Upper limits are set on the values of |VeN| 2 and
|VμN| 2 , where VℓN is the
matrix element describing the mixing of N with the standard model
neutrino of flavor ℓ. These are the first direct limits for N masses
above 500 GeV and the first limits obtained at a hadron collider for N
masses below 40 GeV.
