θ-vacua in two-dimensional quantum chromodynamics

θ вакуумы в двумерной квантовой хромодинамике

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

It is shown that θ-vacua exist in two-dimensional non-Abelian gauge theories, as well as in the Abelian theories.

Riassunto

Si mostra che esistono vuoti θ in teorie di gauge bidimensionali non abeliane, così come in teorie abeliane.

Резюме

Показывается, что θ вакуумы существуют в двумерных неабелевых калибровочных теориях, а также в абелевых теориях.
