Status Report of the MACRO Experiment for the year 2001

In this 2001 status report of the MACRO experiment, results are presented on atmospheric neutrinos and neutrino oscillations, high energy neutrino astronomy, searches for WIMPs, search for low energy stellar gravitational collapse neutrinos, stringent upper limits on GUT magnetic monopoles, nuclearites and lightly ionizing particles, high energy downgoing muons, primary cosmic ray composition and shadowing of primary cosmic rays by the Moon and the Sun.

Neutrino physics and astrophysics with the MACRO detector

After a brief presentation of the MACRO detector we discuss the data on atmospheric neutrinos and neutrino oscillations, on high energy (E> 1 GeV) neutrino astronomy, on indirect searches for WIMPs and low energy (E >7 MeV) stellar collapse neutrinos.

Magnetic monopoles, nuclearites, Q-balls: a qualitative picture

We present qualitative pictures of the structures of magnetic monopoles (MMs), nuclearites (nuggets of strange quark matter, strangelets, surrounded by electrons) and Q-balls (supersymmetric states of squarks, sleptons and Higgs fields). In particular we discuss the relation between their mass and size. MMs, nuclearites and Q-balls could be part of the cold Dark Matter (DM); we consider astrophysical limits on the flux of these particles in the cosmic radiation.
