Tree-level unitarity constraints on heavy neutral leptons
Abstract Heavy neutral leptons (HNLs) can explain the origin of neutrino masses and oscillations over a wide range of masses. Direct experimental probes of HNLs become unfeasible for masses significantly above the electroweak scale. Consequently, the strongest limits arise from the non-observation o...
