Abstract
We investigate the pair-production of RightHanded Neutrinos (RHNs) via a B − L Z boson and present the sensitivity studies of the active-sterile neutrino mixing (|VμN |) at the High-Luminosity run of the LHC (HL-LHC) and a future pp collider (FCC-hh). We focus on RHN states with a mass of 10 − 70 GeV which naturally results in displaced vertices for small |VμN |. Being produced through a mass resonance with MZ ≥ 1 TeV, the RHNs are heavily boosted, leading to collimated decay products that give rise to fat-jets. We investigate the detection prospect of dedicated signatures in the inner detector and the muon spectrometer, namely a pair of displaced fat-jets and the associated tracks, respectively. We find that both the HL-LHC and FCC-hh can be sensitive to |VμN | > 10−6 and |VμN | > 10−7 with the number of events reaching O(10) and O(103), respectively. This allows probing the generation of light neutrino masses through the Seesaw mechanism.
