Weakly Interacting Sub-eV Particle Searches

摘要

We make use of the generation-regeneration or "light shining through a wall" technique in searches for optical-wavelength photons mixing with hypothetical hidden-sector paraphotons in the mass range between 10~(-5) and 10~(-2) electron volts for a mixing parameter greater than 10~(-7) and in sensitive searches for scalar and pseudoscalar coupling of photons to light neutral bosons in the mass range of approximately 1.0 milli-electron volts and coupling strength greater than 10~(-6) GeV~(-1). Additionally, there is an effort underway to use photons in the microwave region using this same technique to make a more sensitive measurement in the mass range of approximately 0.1 milli-electron volts. The equipment in the latter effort will be used to search for galactic halo axions in this same mass range.
