Abstract : We present results of searches for vector and pseudoscalar bosonic super-weakly interacting massive particles (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 ×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/c2 mass range, excluding couplings to electrons with coupling constants of gae>3×10-13 for pseudo-scalar and α′/α>2×10-28 for vector super-WIMPs, respectively. These limits are derived under the assumption that super-WIMPs constitute all of the dark matter in our galaxy.
