Condensates and vacuum structure of adjoint QCD2 Original Research Article

We discuss a two-dimensional SU(N) Yang-Mills theory coupled to massive adjoint fermions for different worlds classified by the integer k = 0, 1,…,N−1. We study the fermion condensate for these unconnected worlds as a function of the parameter k. We show that the condensate as well as the spectrum of the theory do depend on this vacuum parameter k.
