Abstract: (Elsevier)
We study the evolution of cosmic superconducting strings and their decay. We show that they pass by three stages. The last one produces high-energy particles. The size of the loop at this stage is less than 30 pc. If particles can leave the string, and μ 22 is the linear density necessary to explain galaxy formation, the strings are shown to produce isotropic γ radiation in excess of present bounds. However, we show that the produced particles degrade drastically in energy in the magnetic field of the string so that high-energy particles are not produced.
