Query: Constraints on low-mass WIMPs from the EDELWEISS-III dark matter search   We present the results of a search for elastic scattering from galactic dark
matter in the form of Weakly Interacting Massive Particles (WIMPs) in the 4-30
GeV/$c^2$ mass range. We make use of a 582 kg-day fiducial exposure from an
array of 800 g Germanium bolometers equipped with a set of interleaved
electrodes with full surface coverage. We searched specifically for $\sim
2.5-20$ keV nuclear recoils inside the detector fiducial volume. As an
illustration the number of observed events in the search for 5 (resp. 20)
GeV/$c^2$ WIMPs are 9 (resp. 4), compared to an expected background of 6.1
(resp. 1.4). A 90% CL limit of $4.3\times 10^{-40}$ cm$^2$ (resp. $9.4\times
10^{-44}$ cm$^2$) is set on the spin-independent WIMP-nucleon scattering
cross-section for 5 (resp. 20) GeV/$c^2$ WIMPs. This result represents a
41-fold improvement with respect to the previous EDELWEISS-II low-mass WIMP
search for 7 GeV/$c^2$ WIMPs. The derived constraint is in tension with hints
of WIMP signals from some recent experiments, thus confirming results obtained
with different detection techniques.
