Query: Dissipating Cosmic Vortons and Baryogenesis   Grand unified theories can admit cosmic strings with fermion zero modes which
result in the string carrying a current and the formation of stable remnants,
vortons. We consider theories in which the zero modes do not survive a
subsequent phase transition, for example the electroweak transition, resulting
in vorton dissipation. The dissipating vortons can create a baryon asymmetry.
We calculate the asymmetry produced, and show that it is maximised if the
vortons decay just before they dominate the energy density of the Universe. We
further bound the asymmetry produced by the late decay of any relic particle.
