Abstract
Neutrinos can polarize a medium due to their weak interaction. This can manifest itself as an effective induced charge of the neutrino. We show how it is related to the Debye screening length in a plasma, first using the results of the 1-loop calculation of the neutrino electromagnetic vertex and then in general to all orders in and to leading order in the Fermi coupling. We also discuss how the results are modified if the neutrinos have mass -- either Dirac or Majorana type.
