Abstract: An electric field in pure Maxwell theory is stable. However, if there are charged particles in the theory, the electric field decays due to Schwinger pair production. In pure non-Abelian gauge theories, the gauge particles are themselves charged, leading to the question of whether a non-Abelian electric field, such as in a confining string, can be stable. I will discuss electric fields due to certain non-Abelian gauge configurations that are protected from Schwinger pair production and may be candidates for confining strings.
