Resumen

In this work, we study the lepton number violating W boson and top quark decays via intermediate on-shell Majorana neutrinos N j into three charged leptons and a light neutrino. We discuss the neutrino oscillation effects present in the decay due to the small mass gap between the heavy neutrino states (). We focus on a scenario that contains at least two heavy Majorana neutrinos in the mass range . The results indicate that the modulation of the branching ratios as a function of the distance between the vertices may be detected in a future experiment such as High-Luminosity Large Hadron Collider. As a secondary result, the CP-violating phases could be explored.
