Abstract

We investigate the BPS configuration of the multi-D-vortices produced from the D2l32 system. Based on the DBI-type action with a Gaussian-type runaway potential for a complex tachyon field, the BPS limit is achieved when the tachyon profile is thin. The solution allows randomly-distributed n static D-vortices with zero interaction. With the obtained BPS configuration, we derive the relativistic Lagrangian, which describes the dynamics of free massive D-vortices. We also discuss the 90° and the 180° scatterings of two identical D-vortices and present the implications for reconnection in the dynamics of cosmic superstrings.
