The neutrino magnetic moment in the early universe

Summary

We consider a spin-torsion coupling for neutrinos in the early universe and show that a neutrino magnetic moment can be present also for zeromass neutrinos. We make an estimate of this induced magnetic moment just prior to the nucleosynthesis and it happens that it is of the same magnitude as that obtained in the Weinberg-Salam electroweak theory; moreover it is temperature dependent.
