Circumventing Astrophysical Bounds Upon PVLAS Experiment
Abstract
Description
We study the possibility of evading astrophysical bound on light pseudoscalars. We argue that the solar bounds can be evaded if we have a sufficiently strong self-coupling of the pseudoscalars. The required coupling does not conflict with any known experimental bounds. We also show that it is possible to find a coupling range such that the recent PVLAS experiment is not in conflict with any astrophysical bounds.
