Fermions in a Global Monopole Background

Abstract

We study the scattering of fermions in a ``global monopole'' background metric. This is the four-dimensional analogue of the scattering on a cone in three dimensions. The scattering amplitude is exactly obtained. We then study massless fermion-dyon systems in such a background metric. The density of the $S$-wave fermion condensate is found to be given by a constant times the flat space value of Callan and Rubakov.
