Search for dark photon dark matter in the mass range 41 − 74 μ eV using millimeter-wave receiver and radioshielding box
Dark photons have been considered potential candidates for dark matter. The dark photon dark matter (DPDM) has a mass and interacts with electromagnetic fields via kinetic mixing with a coupling constant of χ . Thus, DPDMs are converted into ordinary photons at metal surfaces. Using a millimeter-wav...
