الوصف: | We revisited the computation of the cross section for the $\mu^-\mu^-\to \ell^-\ell^{-}$ $(\ell^-=\tau^-,\, e^-)$ transitions in the presence of new heavy Majorana neutrinos. We focus on scenarios where the masses of the new states are around some few TeV, the so-called low-scale seesaw models. Our analysis is set in a simple model with only two new heavy Majorana neutrinos considering the current limits on the heavy-light mixings. Our results illustrate the difference between the genuine effects of two nondegenerate heavy Majorana states and the degenerate case where they form a Dirac singlet field.
