THE GRAVITATIONAL-FIELD OF A CHARGED GLOBAL MONOPOLE

A charged global monopole formed as a consequence of the spontaneous b reakdown of a global symmetry should have a mass that grows linearly w ith the distance off its core where the gravitational effect of this c onfiguration is equivalent to that of the deficit solid angle in the m etric and the relatively tiny mass at the origin. In this paper it is shown that this small effective mass depends on the charge in that the re exists a negative mass when the charge number Q is less than a crit ical value Q(cr) and that there appears a positive one when Q > Q(cr).
