Abstract

We investigate recent claims concerning a new class of cosmic string solutions in the Weinberg-Salam model. They have the general form of previously discussed semi-local and electroweak strings, but are modified by the presence of a non-zero W-condensate in the core of the string. We explicitly construct such solutions for arbitrary values of the winding number NN. We then prove that they are gauge equivalent to bare electroweak strings with winding number N−1N-1. We also develop new asymptotic expressions for large-NN strings.
