| contents | I show comparisons of the pseudoscalar meson vector form factor from simulations of QCD with $N_c = 3$, 4 and 5 colors and $N_f = 2$ flavors of degenerate mass fermions at a common (matched) fermion mass, lattice spacing, and simulation volume. The dependence of the form factor on the momentum transfer is nearly independent of the number of colors, and is consistent with the expectations of vector meson dominance. |
