Abstract

It is well known that a majorana mass induces a (small) transition magnetic moment. The converse is also true; in this paper we estimate the loop contribution of transition magnetic moments [μ]_αβ to the neutrino mass matrix [m]_αβ. We show that for hierarchical neutrino masses, the contribution of [μ]_{e τ} to [m]_{e τ} can exceed the experimental value of [m]_{e τ}.
