摘要：

The PVLAS anomaly can be explained if there exist millicharged particles of mass less than or similar to 0.1 eV and electric charge epsilon similar to 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. Crown Copyright (c) 2007 Published by Elsevier B.V. All rights reserved.
