Multiple vacua in two-dimensional Yang-Mills theory
A. Bassetto, L. Griguolo, F. Vian
Two-dimensional SU(N) Yang-Mills theory is endowed with a non-trivial vacuum structure (k-sectors). The presence of k-sectors modifies the energy spectrum of the theory and its ins…

Light-front vacuum and instantons in two dimensions
A. Bassetto, L. Griguolo, F. Vian
We review several aspects of Yang-Mills theory (YMT) in two dimensions, related to its perturbative and topological properties. Consistency between light-front and equal-time formu…

Wilson loops in the adjoint representation and multiple vacua in two-dimensional Yang-Mills theory
A. Bassetto, L. Griguolo, F. Vian
with fermions in the adjoint representation is invariant under and thereby is endowed with a non-trivial vacuum structure (k-sectors). The static potential betw…
