Summary of MACRO results on exotic physics
  MACRO was a multi-purpose experiment that took data from 1989 to 2000, at the underground Laboratory of Gran Sasso (Italy). MACRO gave important results/limits concerning: (i) the oscillation of atmospheric neutrinos, also in the non-conventional scenario of violations of Lorentz invariance, (ii) the searches for exotic particles (supermassive GUT magnetic monopoles, nuclearites, WIMPs), (iii) muon physics and astrophysics. A summary of the MACRO results will be presented and discussed, focusing the attention on the exotica searches.
