摘要：

DAMA/LIBRA实验，在I.N.F.N.的Gran Sasso国家实验室进行。在意大利，有一个敏感的质量约250公斤的高放射纯NaI（Tl）。它主要致力于利用与模型无关的暗物质年调制特征研究星系晕中的暗物质粒子。目前的DAMA/LIBRA实验和以前的DAMA/NaI实验（第一代实验的受照质量约为100公斤）迄今为止公布的结果相当于在13个年周期内每年受照1.17吨。它们提供了一个独立于模型的证据，证明了在8.9 σ C. L的星系晕中存在DM粒子。所获得的结果的一个简短的总结和未来的前景提到的实验。

英文摘要：

The DAMA/LIBRA experiment, running at the Gran Sasso National Laboratory of the I.N.F.N. in Italy, has a sensitive mass of about 250 kg highly radiopure NaI(Tl). It is mainly devoted to the investigation of Dark Matter (DM) particles in the Galactic halo by exploiting the model independent DM annual modulation signature. The present DAMA/LIBRA experiment and the former DAMA/NaI one (the first generation experiment having an exposed mass of about 100 kg) have released so far results corresponding to a total exposure of 1.17 ton yr over 13 annual cycles. They provide a model independent evidence of the presence of DM particles in the galactic halo at 8.9 sigma C.L.. A short summary of the obtained results is presented and future perspectives of the experiment mentioned.
