摘要:

氙100实验最近完成了一个暗物质运行与100.9活天的数据,从2010年1月至6月。事件在一个48公斤的基准体积在8.4和44.6 keVnr之间的能量范围进行了分析。在预定义的信号区域中总共发现了三个事件,与背景预测的(1.8 \pm 0.6)事件一致。在此基础上,我们提出了非弹性暗物质的WIMP-核子截面的极限。与目前的数据,我们能够排除所观察到的DAMA/LIBRA调制的解释是由于非弹性暗物质散射碘在90%的置信水平。

英文摘要:

The XENON100 experiment has recently completed a dark matter run with 100.9 live-days of data, taken from January to June 2010. Events in a 48kg fiducial volume in the energy range between 8.4 and 44.6 keVnr have been analyzed. A total of three events have been found in the predefined signal region, compatible with the background prediction of (1.8 \pm 0.6) events. Based on this analysis we present limits on the WIMP-nucleon cross section for inelastic dark matter. With the present data we are able to rule out the explanation for the observed DAMA/LIBRA modulation as being due to inelastic dark matter scattering off iodine at a 90% confidence level.
