Description
The neutrino dipole portal adds a Heavy Neutral Lepton (HNL) coupled to active neutrinos via dipole-like interactions with Standard model electroweak gauge fields. Motivated by the unsolved MiniBooNE, ANITA, and muon g-2 anomalies, the dipole portal provides an alternative way to test the existence of HNLs compared to the minimal model, where HNLs mix with active neutrinos. In this talk, we demonstrate how different future experiments may complementarily explore the parameter space of the dipole portal: neutrino factories (such as DUNE, FASER2) are mainly sensitive to light (< O(5 GeV)) HNLs with relatively large couplings, while collider experiments (LHC and FCC-ee) may probe higher mass HNLs with smaller couplings.
