摘要
We analyze particle production in the spacetime of a chiral cosmic string when it evolves to a static cosmic string configuration. The number of created particles and their energy per unit length of a string are estimated. They appear to be five orders smaller than gravitational particle production in the formation of a static cosmic string but still is rather significant.
