Abstract

We calculate the dynamically generated up quark mass in some QCD-like theories with F=3 light flavors, obtained from supersymmetric QCD perturbed via anomaly mediated supersymmetry breaking. We match the low-energy effective theory to the traditional chiral Lagrangian of QCD and determine the coefficients to next-to-leading order in chiral perturbation theory, while also varying the number of colors N. We find that the dynamically generated up quark mass vanishes in the large N limit, and is small for F
