Majorana Neutrinos — Their Electromagnetic Properties and Neutral Current Weak Interactions

  • Boris Kayser
Part of the Studies in the Natural Sciences book series (SNS, volume 19)


In grand unified theories, the possibility that neutrinos are massive Majorana particles is a rather attractive option. Thus, it becomes interesting to try to build up a picture of the kind of animal a Majorana neutrino is. With that aim in mind, I would like to talk about two aspects of Majorana neutrinos: their electromagnetic properties, and their neutral current weak interactions. Before I do that, I would like to very carefully define what I will mean by a Majorana neutrino, and say a little bit about Majorana-Dirac confusion.
