Transition Radiation from the Neutrino-Photon Interaction in Matter

TL;DR

This paper demonstrates that neutrinos can emit transition radiation when crossing media boundaries due to their effective electromagnetic interactions in matter, within the standard model, independent of exotic properties.

Contribution

It introduces the concept of neutrino-induced transition radiation in matter based on standard model interactions, without requiring new physics.

Findings

Transition radiation occurs for neutrinos crossing media boundaries.

The effect is independent of exotic neutrino properties.

Comparison with neutrinos having intrinsic dipole moments.

Abstract

We show that, because of their effective electromagnetic interaction in matter, transition radiation is emitted whenever neutrinos goes across the boundary between two media with different indices of refraction. This effect occurs in the context of the standard model and does not depend on any exotic neutrino property. We examine such a phenomena and compare it with the transition radiation of a neutrino endowed with an intrinsic dipole moment.
