Author(s): Adi Armoni, Biagio Lucini, Agostino Patella, and Claudio Pica We study quenched SU(N) gauge theories with fermions in the two-index symmetric, antisymmetric and the adjoint representations. Our main motivation is to check whether at large number of colors those theories become nonperturbatively equivalent. We prove the equivalence assuming that the charge-conj... [Phys. Rev.
