标题： Rare Particle Searches with the high altitude SLIM experiment

摘要： 寻找宇宙射线中的稀有粒子仍然是非加速器天体粒子物理学的主要目标之一。 高海拔实验与海平面或地下探测器相比，可以达到更低的质量阈值。 SLIM实验是一个大型核径迹探测器阵列，位于查卡塔亚高原实验室（海拔5290米）。 这里报告了对前236平方米暴露超过3.6年的部分数据的初步分析结果。 该探测器对中间质量磁单极子以及SQM团块和Q球敏感，这些都可能是暗物质候选者。 显示英文摘要

摘要： The search for rare particles in the cosmic radiation remains one of the main aims of non-accelerator particle astrophysics. Experiments at high altitude allow lower mass thresholds with respect to detectors at sea level or underground. The SLIM experiment is a large array of nuclear track detectors located at the Chacaltaya High Altitude Laboratory (5290 m a.s.l.). The preliminary results from the analysis of a part of the first 236 sq.m exposed for more than 3.6 y are here reported. The detector is sensitive to Intermediate Mass Magnetic Monopoles and to SQM nuggets and Q-balls, which are possible Dark Matter candidates.
