Revisiting metastable cosmic string breaking

Revisiting metastable cosmic string breaking

Abstract Metastable cosmic strings appear in models of new physics with a two-step symmetry breaking G → H → 1, where π 1(H) ≠ 0 and π 1(G) = 0. They decay via the monopole-antimonopole pair creation inside. Conventionally, the breaking rate has been estimated by an infinitely thin string approximat...
