Description

We investigate the pair production of right-handed neutrinos from the decay of the additional neutral gauge boson Z′ at a gauged B − L model. Analysing such signal can be recasted from dark photon searches with a corresponding factor of its coupling g′, this gives a upper bound for g′ to be 10−4 for mZ′ under 10 GeV and $10^{−3}$ for mZ′ beyond 10 GeV. As the heavy neutrinos can be longlived as distinctive displaced vertices signatures via seesaw mechanism, an simulation based on Monte Carlo event generator is performed, which shows a sensitivities for VμN< 10−5 with 300 fb−1 assuming g′ = 10−3 and MN = 0.3∗mZ′ at MAPP and LHCb detector.
