Multilepton and lepton jet probes of sub-weak-scale right-handed neutrinos
Multilepton and lepton jet probes of sub-weak-scale right-handed neutrinos
We propose new searches that exploit the unique signatures of decaying sterile neutrinos with masses below ${M}_{W}$ at the LHC, where they can be produced in rare decays of Standard Model gauge bosons. We show that, for few-GeV-scale sterile neutrinos, the LHC experiments can probe mixing angles at the level …
