Search for Bosonic Super-WIMP Interactions with the XENON100 Experiment

Abstract

We present results of searches for vector and pseudo-scalar bosonic super-WIMPs, which are dark matter candidates with masses at the keV-scale, with the XENON100 experiment. XENON100 is a dual-phase xenon time projection chamber operated at the Laboratori Nazionali del Gran Sasso. A profile likelihood analysis of data with an exposure of 224.6 live days $\times$ 34\,kg showed no evidence for a signal above the expected background. We thus obtain new and stringent upper limits in the $(8-125)$\,keV/c${}^2$ mass range, excluding couplings to electrons with coupling constants of $g_{ae}>3\times 10^{-13}$ for pseudo-scalar and ${\alpha }^{\prime }/\alpha >2\times 10^{-28}$ for vector super-WIMPs, respectively. These limits are derived under the assumption that super-WIMPs constitute all of the dark matter in our galaxy.
