# Metastable strings in Abelian Higgs models embedded in non-Abelian theories: Calculating the decay rate

@article{Shifman2002MetastableSI, title={Metastable strings in Abelian Higgs models embedded in non-Abelian theories: Calculating the decay rate}, author={Mikhail Shifman and Alexei V Yung}, journal={Physical Review D}, year={2002}, volume={66}, pages={045012} }

We study the fate of U(1) strings embedded in a non-Abelian gauge theory with the hierarchical pattern of symmetry breaking $G\mathrm{U}(1)$ nothing, $V\ensuremath{\gg}v.$ While in the low-energy limit the Abrikosov-Nielsen-Olesen string (flux tube) is perfectly stable, when considered in the full theory it is metastable. We consider the simplest example: the magnetic flux tubes in SU(2) gauge theory with adjoint and fundamental scalars. First, the adjoint scalar develops a vacuum expectation…
