Anapole dark matter interactions as soft hidden photons

Abstract

We propose a model where the anapole appears as a hidden photon that is coupled to visible matter through a kinetic mixing. For low momentum |p|≪M where M is the cutoff the model (soft hidden photon limit) is reduced to the Ho-Scherrer description. We show that the hidden gauge boson is stable and therefore hidden photons are indeed, candidates for dark matter. Our approach shows that anapole and kinetic mixing terms are equivalent descriptions seen from different scales of energy. Keywords: Dark matter, Hidden photons
