Abstract: We study the low energy behaviour of N=(2,2) supersymmetric gauge theories in1+1 dimensions, with orthogonal and symplectic gauge groups and matters in thefundamental representation. We observe supersymmetry breaking insuper-Yang-Mills theory and in theories with small numbers of flavors. Forlarger numbers of flavors, we discover duality between regular the..
