"Unveiling the Secrets of Hidden Photon Dark Matter: New Study Reveals Kinetic Mixing Constraints"
Originally Published 2 years ago — by Phys.org

Researchers at the California Institute of Technology have set new constraints on the direct detection of hidden photon dark matter, a candidate for dark matter that has a weak interaction with ordinary photons. Their approach involves using quantum-limited amplifiers and low temperatures to reduce the minimal signal levels that can be detected. While their method limits the size of the dish they can use, they hope that the increased sensitivity of their measurement will compensate for this limitation and contribute to the detection of dark photons.
