Superconducting string texture - art. no. 025012

We present a detailed analytical and numerical study of a novel type of sta tic, superconducting, classically stable string texture in a renormalizable topologically trivial massive U(1) gauge model with one charged and one ne utral scalar. An upper bound on the mass of the charged scalar as well as o n the current that the string can carry are established. A preliminary unsu ccessful search for stable solutions corresponding to large superconducting loops is also reported.
