Description

We study the capability of angular and polarization observables to disentangle different new physics contributions to the production of heavy sterile Majorana neutrinos in the lepton number violating channels $e^{-}p\to l_j^{+}+3jets$ ($l_j$≡e,μ) and $e^{+}{e}^{-}\to {\tau }^{+}{\tau }^{+}+4jets$ in electron-proton and electron-positron colliders. This is done investigating the angular and polarization trails of effective operators with distinct Dirac-Lorentz structure contributing to the Majorana neutrino production, which parameterize new physics from a higher energy scale.
