Long-lived TeV-scale right-handed neutrino production at the LHC in gauged $U(1{)}_X$ model

Arindam Das, P. S. Bhupal Dev, Nobuchika Okada

A gauged $U(1{)}_X$ extension of the Standard Model is a simple and consistent framework to naturally incorporate three right-handed neutrinos (RHNs) for generating the observed ligh…
