Proposal for a Search for Cosmic Axions Using an Optical Cavity

Proposal for a Search for Cosmic Axions Using an Optical Cavity A high finesse optical cavity can be used to search for cosmic axions in the mass range 10 - 6 < m a < 10 - 4 eV . Either a two-arm or a single-arm cavity is suitable, and in either case the signal appears as resonant sidebands imposed on the carrier. Assuming for the local axion density the usual figure of ρ a = 500 Mev / cm 3 , the KSVZ axion line g a γ γ / m a = 0.4 GeV - 2 , can be reached over the full mass range in a 1 yr search. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review Letters American Physical Society (APS)

Abstract

A high finesse optical cavity can be used to search for cosmic axions in the mass range 10 - 6 < m a < 10 - 4 eV . Either a two-arm or a single-arm cavity is suitable, and in either case the signal appears as resonant sidebands imposed on the carrier. Assuming for the local axion density the usual figure of ρ a = 500 Mev / cm 3 , the KSVZ axion line g a γ γ / m a = 0.4 GeV - 2 , can be reached over the full mass range in a 1 yr search.
