摘要:

韩国隐形质量搜索(KIMS)实验利用在阳阳地下实验室用低本底CsI(Tl)晶体获得的3409 kgd照射量的数据,提出了WIMP-核子截面的新极限。得到了纯质子情况下自旋相关相互作用的最严格极限。对于质量大于20 GeV/c^2的WIMP,自旋无关和自旋相关相互作用的DAMA信号区都被晶体振荡器的单个实验排除在外。

英文摘要:

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.
