摘要：The search for rare particles in the cosmic radiation remains one of the main aims of nonaccelerator
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 the first 227 m2 exposed for more than 3.6 y are here reported.
The detector is sensitive to Intermediate Mass Magnetic Monopoles, 105 < mM < 1012 GeV, and
to SQM nuggets and Q-balls, which are possible Dark Matter candidates.
