Searches for electron interactions induced by new physics in the EDELWEISS-III germanium bolometers

Eric Armengaud, C. Augier, A. Benoı̂t, L. Bergé et autres

We make use of the EDELWEISS-III array of germanium bolometers to search for electron interactions at the keV scale induced by phenomena beyond the Standard Model. A 90% C.L. lower limit is set on the electron lifetime decaying to invisibles, $\ensuremath{\tau}>1.2\ifmmode\times\else\texttimes\fi{}{10}^{24}\text{ }\text{ …

Optimizing EDELWEISS detectors for low-mass WIMP searches

Q. Arnaud, Eric Armengaud, C. Augier, A. Benoı̂t et autres

The physics potential of EDELWEISS detectors for the search of low-mass weakly interacting massive particles (WIMPs) is studied. Using a data-driven background model, projected exclusion limits are computed using frequentist and multivariate analysis approaches, namely, profile likelihood and boosted decision tree. Both …

Signals induced by charge-trapping in EDELWEISS FID detectors: Analytical modeling and applications

Q. Arnaud, Eric Armengaud, C. Augier, A. D. Benoit et autres

The EDELWEISS-III direct dark matter search experiment uses cryogenic HP-Ge detectors Fully covered with Inter-Digitized electrodes (FID). They are operated at low fields (< 1 V/cm), and as a consequence charge-carrier trapping significantly affects both the ionization and heat energy measurements. This …

Measurement of the cosmogenic activation of germanium detectors in EDELWEISS-III

the EDELWEISS Collaboration, Eric Armengaud, Q. Arnaud, C. Augier et autres

We present a measurement of the cosmogenic activation in the germanium cryogenic detectors of the EDELWEISS III direct dark matter search experiment. The decay rates measured in detectors with different exposures to cosmic rays above ground are converted into production rates of …

Constraints on low-mass WIMPs from the EDELWEISS-III dark matter search

Eric Armengaud, Q. Arnaud, C. Augier, A. Benoît et autres

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 …
