Search for heavy Majorana neutrinos in μ±μ± + jets events in proton-proton collisions at s=8 TeV
(2015-07-02)
A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two muons of the same charge and two jets (μ±μ±jj). The data correspond to an integrated luminosity of 19.7 fb-1 of proton-proton ...
