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. We restrict our attention to states in the non-zero isospin sector, evaluating the masses associated with the ground-state and first excitation in the pseudoscalar, vector, scalar, and axial vector channels. Our results are based on a new set of simulations of four dimensional SU (N) Yang-Mills theories with the number of colors ranging from N= 2 to N= 17; thespectraandthedecayconstantsarecomputedinthequenchedapproximation (which becomes exact in the’t Hooft limit) using Wilson fermions. After discussing the extrapolations to the chiral and large-N limits, we present a comparison of our results to some of the numerical computations and analytical predictions available in the literature—including, in particular, those from holographic computations.
