Abstract
The purpose of this workshop is to discuss various aspects of superheavy magnetic monopoles, Coleman and Goldhaber have told us what a grand unified monopole is. It is a topologically-stable, classical configuration of gauge and Higgs fields which is present in the low-energy theory when a semisimple group G breaks down to a group G’ which contains a U(1) factor.1 The long-range fields of this configuration are those of a magnetic monopole with magnetic charge h = n(2π/e) ≃ n(69e), n = ±1, ±2, ..., and the energy associated with this configuration is 0(M/α) where M is the scale of spontaneous symmetry breaking (SSB) and α is the gauge coupling constant. For SU(5) M ≃ 1014 GeV, and the monopole mass m ≃ 1016 GeV (≃10-8 grams!). In my review I will discuss where the magnetic monopoles with us today came from and how many we should expect.
