Hidden photon CDM search at Tokyo


الملخص بالإنكليزية

We report on a search for hidden photon cold dark matter (HP CDM) using a novel technique with a dish antenna. We constructed two independent apparatus: one is aiming at the detection of the HP with a mass of $sim,rm{eV}$ which employs optical instruments, and the other is for a mass of $sim5times10^{-5}, rm{eV}$ utilizing a commercially available parabolic antenna facing on a plane reflector. From the result of the measurements, we found no evidence for the existence of HP CDM and set upper limits on the photon-HP mixing parameter $chi$.
