Displaced heavy neutral lepton from new Higgs doublet
Abstract Heavy neutral leptons N are introduced to explain the tiny neutrino masses via the seesaw mechanism. For proper small mixing parameter $$V_{\ell N},$$ V ℓ N , the heavy neutral leptons N become long-lived, which leads to the displaced vertex signature at colliders. In this paper, we conside...
