We study U (1) and SU (2) lattice gauge theories in an external constant background field. For the non-abelian case we look for the effects of unstable modes on the vacuum energy density.

We study U (1) and SU (2) lattice gauge theories in an external constant background field. For the non-abelian case we look for the effects of unstable modes on the vacuum energy density.File in questo prodotto:
