Abstract
We study, within an approximate Inverse Amplitude Method to unitarize Chiral Perturbation Theory, whether low mass scalar mesons can survive in large N_c regime, and show that vector mesons such as \rho and K^* survive as narrow width resonances, but all of the scalar meson nonet below 1GeV fade out as N_c becomes large.
