Popis: | 36th International Cosmic Ray Conference, ICRC 2019, Madison, United States, 24 Jul 2019 - 1 Aug 2019; Proceedings of Science / International School for Advanced Studies (ICRC2019), 517 (2020). An additional U(1) symmetry predicted in theories beyond the Standard Model of particle physics can give rise to hidden (dark) photons. Depending on the mass and density of these hidden photons, they could account for a large fraction of the Dark Matter observed in the Universe. When passing through an interface of materials with different dielectric properties, hidden photons are expected to produce a tiny flux of photons. The wavelength of these photons is directly related to the mass of the hidden photons. In this contribution we report on measurements covering the visible and near-UV spectrum, corresponding to a dark photon mass in the eV range. The data were taken with the FUNK experiment using a spherical mirror of $\sim$ 14 m$^2$ total area built up of 36 aluminum segments. Published by SISSA, Trieste |
