Abstract

We present preliminary results from our calculation of the low energy constants (LECs) of the chiral effective theory for 3, 4 and 5 color QCD with N_f=2 dynamical fermion flavors. We simulate with clover fermions over a range of lattice couplings and quark masses. We observe the expected N_c scaling for the LECs appropriate to the condensate B and pseudoscalar decay constant F. The range of quark masses over which leading order chiral perturbation theory describes the data grows as N_c rises.
