Effects of Cosmic String Velocities and the Origin of Globular Clusters
  With the hypothesis that cosmic string loops act as seeds for globular
clusters in mind, we study the role that velocities of these strings will play
in determining the mass distribution of globular clusters. Loops with high
enough velocities will not form compact and roughly spherical objects and can
hence not be the seeds for globular clusters. We compute the expected number
density and mass function of globular clusters as a function of both the string
tension and the peak loop velocity, and compare the results with the
observational data on the mass distribution of globular clusters in our Milky
Way. We determine the critical peak string loop velocity above which the
agreement between the string loop model for the origin of globular clusters
(neglecting loop velocities) and observational data is lost.
