| Abstract | Abstract: We calculate the pion and ρ meson masses in quenched SU(N) gauge theories for N = 2,3,4 and 6. Extrapolating these results to the chiral and large-N limits, we find mρ = (1.670 ±0.024) √ σ for the ρ meson mass at a fixed lattice spacing a ≈ 0.2093σ −1/2 ≈ 0.093 fm, where we use the (arbitrary) value (444 MeV) 2 for the string tension. We estimate a continuum limit large-N value, mρ = (1.77 ± 0.05) √ σ. We find 1/N 2 corrections to be small and we compare our results to predictions from AdS/QCD. |
