Title: Shortcuts in particle production in a toroidally compactified space-time
Author: Da Silva, JMH
Da Rocha, R
Abstract: We investigate the particle production in a toroidally compactified space-time due to the expansion of a Friedmann cosmological model in R-3 x S-1 outside a U(1) local cosmic string. The case of a Friedmann space-time is also investigated where torsion is incorporated in the connection. We present a generalization to toroidal compacti. cation of p extra dimensions, where the topology is given by R-3 x T-p. Some implications are presented and discussed. Besides the dynamics of space-time, we investigate in detail the physical consequences of the topological transformations.
