Dynamic fermion flavor mixing through transition dipole moments

TL;DR

This paper explores how external electromagnetic fields can induce flavor mixing in Majorana neutrinos via transition dipole moments, leading to dynamical mass eigenstates and potential implications for quark sector extensions.

Contribution

It introduces a novel mechanism for neutrino flavor mixing driven by electromagnetic interactions, extending the concept to three flavors and quark sectors.

Findings

Flavor mixing can be dynamically driven by electromagnetic fields.

Strong fields significantly affect the flavor rotation matrix.

Extensions to quark sector are proposed.

Abstract

We show that Majorana neutrino flavor mixing can be driven by transition dipole moments in the presence of external electromagnetic fields. We demonstrate the sensitivity of the rotation mixing matrix to strong fields obtaining dynamical mass eigenstates in the two-flavor model. The three-flavor case and extensions to the quark sector are introduced.
