dc.description.abstractA search is performed for heavy Majorana neutrinos (N) using an event signature defined by two muons of the same charge and two jets (μ[superscript ±]μ[superscript ±]jj). The data correspond to an integrated luminosity of 19.7 fb[superscript −1] of proton–proton collisions at a center-of-mass energy of 8 TeV, collected with the CMS detector at the CERN LHC. No excess of events is observed beyond the expected standard model background and upper limits are set on |V[subscript μN]|[superscript 2] as a function of Majorana neutrino mass m[subscript N] for masses in the range of 40–500 GeV, where V[subscript μN] is the mixing element of the heavy neutrino with the standard model muon neutrino. The limits obtained are |V[subscript μN]|[superscript 2]<0.00470 for m[subscript N]=90 GeV, |V[subscript μN]|[superscript 2]<0.0123 for m[subscript N]=200 GeV, and |V[subscript μN]|[superscript 2]<0.583 for m[subscript N]=500 GeV. These results extend considerably the regions excluded by previous direct searches.en_US
