Stability of Modified Electroweak Strings
Luis Masperi · Ariel Megevand
Abstract
We discuss the stability of an electroweak string with axions in its core, which give to the configuration a quasi-topological property, and compare it with other modifications using instantons in the thin wall approximation.
