I present a calculation of the topological susceptibility χT in SU(Nc) gauge theory with Nc = 3–5 colors and Nf = 2 degenerate flavors of fermions. The results lie on a common curve when expressed in terms of the combination Ncm2PSt0 where mPS is the pseudoscalar meson mass and t0 is the flow parameter. χT approaches its quenched value as the pseudoscalar mass becomes large. The lattice simulations use clover fermions. They are done at a single lattice spacing, roughly matched across Nc, and over a restricted range of fermion masses.
