Search for hidden-photon dark-matter with FUNK

Andrianavalomahefa, Arnaud; Veberič, D.

Abstract (englisch):
The FUNK (Finding $U(1)$s of Novel Kind) experiment was built to search direct evidences for hidden-photon (HP) dark-matter. We use a $15\,\mathrm{m}^2$ spherical metallic mirror as a HP-to-photon converter via Maxwellian-like transition.
Signals are expected to come together as single photon events at the radius point where we mounted a low-noise photomultiplier.
We scanned the whole optical range of frequencies with extension in far-UV and looked for HP with masses between 2 and 8 eV.
In our preliminary results, we found no events excess but provide the up-to-date strongest limit for HP direct searches in this region.
