Radiative neutrino transition $\nu \to \nu \gamma$ in strongly magnetized plasma

TL;DR

This paper investigates how strongly magnetized electron-positron plasma affects the neutrino radiative transition, showing that plasma and magnetic fields together reduce neutrino energy and momentum losses compared to magnetic fields alone.

Contribution

It provides a detailed calculation of neutrino transition probabilities considering plasma effects, photon dispersion, and resonances, which was not previously addressed.

Findings

Plasma and magnetic field together decrease neutrino energy loss.

Photon dispersion and resonance effects are significant near the transition.

Neutrino momentum loss is also reduced in plasma conditions.

Abstract

The influence of strongly magnetized electron-positron plasma on the radiative neutrino transition $\nng$ is investigated. The probability and mean losses of the neutrino energy and momentum are calculated taking account of the photon dispersion and large radiative corrections near the resonance. It is shown that the combined effect of plasma and strong magnetic field decreases the probability and mean values of the neutrino energy and momentum loss in comparison with these values obtained in pure magnetic field.
