Metastable cosmic strings produce a gravitational wave background that is best modeled with three parameters (string tension Gμ plus independent time scales t_LB and t_NC), yielding a compact analytical spectrum when t_LB greatly exceeds t_NC.

Thermal effects shift the PTA-compatible parameter region in a minimal dark-sector model to lower dark fine-structure constant and higher monopole-to-string-tension ratio by making thermally induced nucleation the dominant decay channel for metastable Z-strings.
Classical instabilities in metastable strings from two-step symmetry breaking can restrict the viable parameter space for explaining the PTA gravitational wave signal.
