abstract
We calculate the probability of destruction of a metastable string by collisions of the Goldstone bosons, corresponding to the transverse waves on the string. We find a general formula that allows to determine the probability of the string breakup by a collision of arbitrary number of the bosons. We find that the destruction of a metastable string takes place only in collisions of even number of the bosons, and we explicitly calculate the energy dependence of such process in a two-particle collision for an arbitrary relation between the energy and the largest infrared scale in the problem, the length of the critical gap in the string.

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.
