Searching for Millicharged Particles with Superconducting Radio-Frequency Cavities
arXiv:2001.02679 · doi:10.1103/PhysRevD.102.035010
Abstract
We demonstrate that superconducting radio-frequency cavities can be used to create and detect millicharged particles and are capable of extending the reach to couplings several orders of magnitude beyond other laboratory based constraints. Millicharged particles are Schwinger pair-produced in driven cavities and quickly accelerated out of the cavity by the large electric fields. The electric current generated by these particles is detected by a receiver cavity. A light-shining-through-walls experiment may only need to reanalyze future data to provide new constraints on millicharged particles.
