Plasma induced neutrino spin flip via the neutrino magnetic moment

TL;DR

This paper investigates how plasma environments influence neutrino spin flip processes mediated by the neutrino magnetic moment, emphasizing the importance of considering both neutrino and photon dispersion effects for accurate analysis.

Contribution

It highlights the necessity of including both neutrino and photon dispersion in medium to properly analyze neutrino spin flip and related radiative processes.

Findings

Importance of medium effects on neutrino magnetic moment interactions

Clarification of physical consistency in neutrino spin flip modeling

Abstract

The neutrino spin flip radiative conversion processes nu_L -> nu_R + gamma^* and nu_L + gamma^* -> nu_R in medium are considered. It is shown in part that an analysis of the so-called spin light of neutrino without a complete taking account of both the neutrino and the photon dispersion in medium is physically inconsistent.
