Description
We present preliminary results for a lattice study of the chiral and continuum limit of pseudoscalar mass and decay constant for $SU(N_c)$ gauge theory with $N_c=3,4,5$ colors and $N_f=2$ degenerate fermions. Clover fermions are used. We fit these observables to predictions of Wilson chiral perturbation theory. Model-averaging is used to determine an appropriate range of quark masses for the fits. We extrapolate our results to large $N_c$. The goal is to produce continuum numbers for the large $N_c$ limit of QCD, and to compare our results with other approaches to this limit
