Cosmic String Loops, Large and Small
We extend our earlier model of the small scale structure of cosmic string
networks through an improved treatment of the separation of long and short
scales. We find that the production of small loops (at the gravitational
radiation scale) is a robust feature of string networks, in addition to a
population of loops near the horizon scale. We obtain quantitative agreement
with the scaling of loop production functions as found in simulations by two
groups.Comment: 13 pages, 3 jpg figures. v2: reference moved, note adde
