Quantum current dissipation in superconducting strings and vortons

In this work, the current stability is discussed for cosmic strings with bosonic superconductivity. A non-vanishing curvature of string generally induce quantum instability current-carrying particle. Its decay rates are explored various types model parameters, curved shapes, and processes. As a cosmological application, examined superconducting in network also vortons by evaluating their evolution. The zero mode hence vorton cannot be stable cases, e.g., hierarchy between particle mass off tension or sizable couplings to light species such as Standard Model particles.
