Mass perturbation theory in the 2-flavor Schwinger model with opposite masses with a review of the background
Abstract I discuss the 2-flavor Schwinger model with θ = 0 and small equal and opposite fermion masses (or θ = π with equal masses). The massless model has an unparticle sector with unbroken conformal symmetry. I argue that this special mass term modifies the conformal sector without breaking the co...
