QCD meson spectrum in the large NC limit
G. Grignani, D. Marmottini, P. Sodano
Abstract
The low energy mass spectrum of QCD in the large NC limit is computed. The low-lying states in the meson spectrum are explicitly evaluated up to the fourth order in the strong coupling perturbative expansion. The 't Hooft limit is smooth and the meson masses are in very good agreement with the experimental values.
