Scientific paper

We numerically investigate collisions of cosmic strings carrying different winding numbers. We find that for strings with winding numbers n1 and n2, intercommutation occurs by peeling a string of winding number ||n1-n2|| from the string with the larger winding number. The resulting string connects the original colliding strings to form a state of three joined strings, but because of the peeling the eventual result is a reduction in the winding numbers of the network. Stable astrophysical strings with large winding number are thus unlikely to persist. All simulations have gauge/scalar-field mass ratio =2. .AE
