Search for Dark Photon Dark Matter in the Mass Range 41--74 \(\mu\mathrm{eV}\) 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 \(\chi\). Thus, DPDMs are converted into ordinary photons at metal surfaces. Using a millimet...

Summary: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 \(\chi\). Thus, DPDMs are converted into ordinary photons at metal surfaces. Using a millimeter-wave receiver set in a radioshielding box, we performed experiments to detect the conversion photons from the DPDM in the frequency range 10--18 GHz, which corresponds to a mass range 41--74 \(\mu\mathrm{eV}\). We found no conversion photon signal in this range and set the upper limits to \(\chi < (0.5\text{--}3.9) \times 10^{-10}\) at a 95% confidence level.
