Abstract
A class of grand unified theories with symmetry breaking scale of orde r 10(16) GeV have a Hi,ags particle with mass in the TeV scale. The co smology of such theories is very different from usual. We study the co smic strings obtained in such theories. These strings are much fatter than usual and their mass per unit length is reduced, resulting in a s ignificant reduction in their cosmological effects. We also study the temperature evolution of such models. (C) 1998 Elsevier Science B.V. A ll rights reserved.
