Can Low Mass Scalar Meson Nonet Survive in Large Nc Limit ?
Masayuki Uehara
Abstract
We study, within an approximate Inverse Amplitude Method to unitarize Chiral Perturbation Theory, whether low mass scalar mesons can survive in large Nc regime, and show that vector mesons such as ρand K* survive as narrow width resonances, but all of the scalar meson nonet below 1GeV fade out as Nc becomes large.
