Description
We study stabilization of an unstable cosmic string associated with
spontaneously broken U(1) R-symmetry, which otherwise causes a
dangerous roll-over process. We demonstrate that in a gauge mediation
model, messengers can receive enough corrections from the thermal
plasma of the supersymmetric standard model particles to stabilize the
unstable modes of the string.
