First limit on WIMP cross section with low background CsI(Tl) crystal detector

چکیده
The Korea Invisible Mass Search (KIMS) collaboration has been carrying out WIMP search experiment with CsI(Tl) crystal detectors at the YangYang Underground Laboratory. A successful reduction of the internal background of the crystal was done and a good pulse shape discrimination was achieved. We report the first result on WIMP search obtained with 237 kg·days data using one full-size CsI(Tl) crystal of 6.6 kg mass.

The Korea Invisible Mass Search (KIMS) experiment presents new limits on the WIMP-nucleon cross section using data from an exposure of 3409 kg·d taken with low-background CsI(Tl) crystals at Yangyang Underground Laboratory. The most stringent limit on the spin-dependent interaction for a pure proton case is obtained. The DAMA signal region for both spin-independent and spin-dependent interactio...
متن کاملNew limits on interactions between weakly interacting massive particles and nucleons obtained with CsI(Tl) crystal detectors.
New limits are presented on the cross section for weakly interacting massive particle (WIMP) nucleon scattering in the KIMS CsI(Tℓ) detector array at the Yangyang Underground Laboratory. The exposure used for these results is 24 524.3 kg·days. Nuclei recoiling from WIMP interactions are identified by a pulse shape discrimination method. A low energy background due to alpha emitters on the crys...

متن کاملν̄e− e− Scattering Cross-Section and Constraints on New Physics with a CsI(Tl) Crystal Array at the Kuo-Sheng Reactor Laboratory
The ν̄e− e− elastic scattering cross-section was measured with a CsI(Tl) scintillating crystal detector array with a total mass of 187 kg at the Kuo-Sheng Nuclear Power Station. The detectors were exposed to a reactor ν̄e flux of 6.4×1012 cm−2s−1 originated from a core with 2.9 GW thermal power. The physics motivations, conceptual design, detector hardware, data analysis and background understand...
