论文摘要

总结了由Dama Deep Underground在Gran Sasso实验室中衡量的长期独立的年度调制效应,并总结了不同的实验配置,并且将强调观点。 Dama/libra-phase2设置,$ \ simeq $ 250 kg Haped Radio-Pure NAI(TL)证实了一个信号的证据,该信号符合High C.L.的模型独立暗物质年度调制签名的所有要求;在22个年度周期中,全部暴露量为2.86吨$ \ times $ yr。该实验目前是在Dama/libra-phase2授权配置中收集数据,并具有较低的软件能量阈值。其他最新主张很快就会发表评论。

The long-standing model-independent annual modulation effect measured by DAMA deep underground at Gran Sasso Laboratory with different experimental configurations is summarized and perspectives will be highlighted. DAMA/LIBRA-phase2 set-up, $\simeq$ 250 kg highly radio-pure NaI(Tl) confirms the evidence of a signal that meets all the requirements of the model independent Dark Matter annual modulation signature at high C.L.; the full exposure is 2.86 ton $\times$ yr over 22 annual cycles. The experiment is currently collecting data in the DAMA/LIBRA-phase2 empowered configuration with an even lower software energy threshold. Other recent claims are shortly commented.
