Limits on WIMP-nucleon interactions with CsI(Tl) crystal detectors

Lee, H. S., Bhang, H. C., Choi, J. H. et al.

Understand

The Korea Invisible Mass Search(KIMS) experiment presents new limits on WIMP-nucleon cross section using the data from an exposure of 3409 kgd taken with low background CsI(Tl) crystals at Yangyang underground laboratory.

  • The most stringent limit on the spin dependent interaction for pure proton case is obtained.
  • The DAMA signal region for both spin independent and spin dependent interactions for the WIMP mass higher than 20 GeV/c^2are excluded by the single experiment with crystal scintillators.
