从第一批ZEPLIN-II数据看自旋相关的WIMP-核子截面的极限

Limits on spin-dependent WIMP-nucleon cross-sections from the first ZEPLIN-II data

G. J. Alner et al.

摘要:

ZEPLIN-II实验的第一次地下数据运行为直接搜索暗物质的两相氙探测器的核反冲率设定了限制。本文将计算结果转化为与自旋有关的WIMP-质子和WIMP-中子截面的极限。WIMP-中子截面曲线的最小值对应于WIMP质量约为65 GeV时的0.07 pb。

英文摘要:

The first underground data run of the ZEPLIN-II experiment has set a limit on the nuclear recoil rate in the two-phase xenon detector for direct dark matter searches. In this paper the results from this run are converted into the limits on spin-dependent WIMP-proton and WIMP-neutron cross-sections. The minimum of the curve for WIMP-neutron cross-section corresponds to 0.07 pb at a WIMP mass of around 65 GeV.
