First broadband search for fixed-polarization dark photon dark matter with GigaBREAD

Jialin Yu, Stefan Knirck, Gabe Hoshino +4

We present the first search for fixed-polarization dark photon (DP) dark matter in the 44-52$\mu \mathrm{eV}$ mass range, corresponding to 10.7-12.5GHz. GigaBREAD is a room-temperatur…
