Approaching the Chiral and Continuum Limit of Large-N QCD

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 Nf=2N_f=2 dynamical fermion flavors. We simulate with clover fermions over a range of lattice couplings and quark masses. We observe the expected NcN_c scaling for the LECs appropriate to the condensate BB and pseudoscalar decay constant FF. The range of quark masses over which leading order chiral perturbation theory describes the data grows as NcN_c rises.
