Abstract
A search for hidden photon cold dark matter (HP CDM) using a new technique with a dish antenna is reported. From the result of the measurement, we found no evidence for the existence of HP CDM and set an upper limit on the photon-HP mixing parameter $Ï$ of $\sim 6\times 10^{-12}$ for the hidden photon mass $m_γ= 3.1 \pm 1.2$ eV.
