Description
BREAD is a reflector-based axion detection concept which seeks to perform broadband searches for axions and axion-like particles at frequencies which are not accessible to resonant cavity experiments due to scaling limitations at small wavelengths. We present recent results from GigaBREAD, a gigahertz pilot experiment which probed axion-like particles and dark photons in the $\sim 50 \ \mu\mathrm{eV}$ range. We have completed a room-temperature search for dark photons using the GigaBREAD apparatus [PRL 132 (2024) 131004]. Last year, we integrated GigaBREAD into a 4 T solenoidal magnet at Argonne National Laboratory to conduct a room-temperature search for axion-like particles [PRL 134 (2025) 171002]. We also discuss future efforts which seek to implement the BREAD reflector concept with higher sensitivities and in different frequency regimes.
