The authors' main claim These data improve the exclusion limits derived from other germanium diode experiments in the ~50 GeV DAMA region, and show that with a moderate improvement of the background below 10 keV, the DAMA region may be tested with an additional 1 kg-year of exposure.

The IGEX Collaboration enriched 76Ge double-beta decay detectors are currently operating in the Canfranc Underground Laboratory with an overburden of 2450 m.w.e. A recent upgrade has made it possible to use them in a search for WIMPs. A new exclusion plot has been derived for WIMP-nucleon spin-independent interaction. To obtain this result, 30 days of data from one IGEX detector, which has an energy threshold of ~4 keV, have been considered. These data improve the exclusion limits derived from other germanium diode experiments in the ~50 GeV DAMA region, and show that with a moderate improvement of the background below 10 keV, the DAMA region may be tested with an additional 1 kg-year of exposure.

The paper

Original abstract

The IGEX Collaboration enriched 76Ge double-beta decay detectors are currently operating in the Canfranc Underground Laboratory with an overburden of 2450 m.w.e. A recent upgrade has made it possible to use them in a search for WIMPs. A new exclusion plot has been derived for WIMP-nucleon spin-independent interaction. To obtain this result, 30 days of data from one IGEX detector, which has an energy threshold of ~4 keV, have been considered. These data improve the exclusion limits derived from other germanium diode experiments in the ~50 GeV DAMA region, and show that with a moderate improvement of the background below 10 keV, the DAMA region may be tested with an additional 1 kg-year of exposure.

Direct and indirect limits on the electro-magnetic form factors of WIMPs
hep-ph 2000-03 conditional novelty 5.0 of 10

Using direct-detection and neutrino-flux limits, the authors bound the magnetic dipole, electric dipole, quadrupole, anapole, charge radius, and polarizability of a 100 GeV WIMP.
Direct Detection of Dark Matter Electromagnetic Dipole Moments
hep-ph 2010-07 conditional novelty 4.0 of 10

A fermionic dark matter particle with a magnetic dipole moment and mass near 10 GeV can simultaneously account for the DAMA modulation signal and the null results of CDMS and XENON.
