Distinguishing (Dirac or Majorana) neutrinos in purely leptonic decays of leptons

Yao Yu, Bai-Cian Ke

We investigate purely leptonic decays of leptons ${ł}^{\prime -}\to l^{-}{\bar{\nu }}_l{\nu }_{l^{\prime }}$ to distinguish Dirac or Majorana neutrinos. We derive the differences of the decay width…
