Abstract
In this talk we will review the different observables we have in order to distinguish between the Dirac or Majorana nature of neutrinos and their current status. On this direction, we studied the radiative leptonic decay $\ell\to\ell’\nu\bar{\nu}\gamma$ motivated by the novel method proposed in PRD 105 (2022), 113006, taking an specific kinematic configuration in order to avoid the constraint imposed by the pDMCT. Our approach demonstrates that, in the back-to-back kinematic configuration (for the ℓ′−γ and ν−νˉ systems, respectively), the distinction between Dirac and Majorana cases disappears when the inaccessible neutrino angle is integrated out.
