Using lattice QCD with 3 to 6 colors and four quark flavors, the paper measures pion-pion scattering phase shifts and finds evidence consistent with a virtual bound state in one channel at three colors.

abstract
I show comparisons of the pion - pion scattering length in the isospin - two channel from simulations of of QCD with $N_c = 3$, 4 and 5 colors and $N_f = 2$ flavors of degenerate mass fermions. The scattering length varies as $1/N_c$, as expected from large $N_c$ counting arguments.

Results on meson-meson scattering at large $N_\text{c}$
Using lattice QCD with 3 to 6 colors and four quark flavors, the paper measures pion-pion scattering phase shifts and finds evidence consistent with a virtual bound state in one channel at three colors.
