A simple explanation of the PVLAS anomaly in spontaneously broken mirror models

High Energy Physics - Phenomenology 2008-11-26 v2

Abstract

The PVLAS anomaly can be explained if there exist millicharged particles of mass <0.1\stackrel{<}{\sim} 0.1 eV and electric charge ϵ106e\epsilon \sim 10^{-6} e. We point out that such particles occur naturally in spontaneously broken mirror models. We argue that this interpretation of the PVLAS anomaly is not in conflict with astrophysical constraints due to the self interactions of the millicharged particles which lead them to be trapped within stars. This conclusion also holds for a generic paraphoton model.
