We review the theoretical developments and conceptual advances that stemmed from the
generalization of QCD to the limit of a large number of color charges, originally proposed by't …

We review recent progress in the study of the large N_c N c limit of gauge theories from
lattice simulations. The focus is not only the planar limit but also the size of O (N_c^-1) O (N c …

A bstract We present the results of a systematic, first-principles study of the spectrum and
decay constants of mesons for different numbers of color charges N, via lattice computations …

A bstract We present the result of our computation of the lowest lying meson masses for SU
(N) gauge theory in the large N limit (with N f/N→ 0). The final values are given in units of the …

We perform an ab initio calculation of the N_c N c scaling of the low-energy couplings of the
chiral Lagrangian of low-energy strong interactions, extracted from the mass dependence of …

Results are presented for hadron spectroscopy with gauge groups SU (N) with N= 3, 5, 7.
Calculations use the quenched approximation. Lattice spacings are matched using the static …

We explain how to compute meson masses in the large N limit using the twisted Eguchi–
Kawai model. A very simple formula is derived, and we show how it leads in a fast and …

Baryon masses at varying values of N c and light quark masses are studied with lattice QCD
and the results are analyzed in a low-energy effective theory based on a combined …

The variation of the resonance poles, ie, the mass and width, originating from changing the
values of NC, the number of the QCD colors, provide an intuitive theoretical method to …
