LHC search for right-handed neutrinos in Z ′ models
Abstract We consider right-handed neutrino pair production in generic Z ′ models. We propose a new, model-independent analysis using final states containing a pair of same-sign muons. A key aspect of this analysis is the reconstruction of the RH neutrino mass, which leads to a significantly improved...

| Summary: | Abstract We consider right-handed neutrino pair production in generic Z ′ models. We propose a new, model-independent analysis using final states containing a pair of same-sign muons. A key aspect of this analysis is the reconstruction of the RH neutrino mass, which leads to a significantly improved sensitivity. Within the U1B−L3 $$ \mathrm{U}{(1)_{\left(B-L\right)}}_{{}_3} $$ model, we find that at the HL-LHC it will be possible to probe RH neutrino masses in the range 0.2≲MNR≲1.1 $$ 0.2\lesssim {M}_{N_R}\lesssim 1.1 $$ TeV. |
