| contents | In arXiv:2305.14140 [hep-ph] the authors analyze the radiative leptonic decay $\ell^- \to ν_\ell \, \overlineν_{\ell'} \, \ell^{\prime -} \, γ$ to distinguish between Dirac and Majorana nature of neutrinos. They utilize the back-to-back kinematics for this purpose, a special kinematic configuration which we first proposed in our paper arXiv:2106.11785 [hep-ph]. Here we point out how and why their analysis of the back-to-back configuration is incorrect. This makes their conclusion and comments invalid and untenable. |
