Les We present a new perspective on the scalar meson puzzle from spontaneous breaking of chiral symmetry beyond BCS. We find that going beyond BCS does not produce a systematic shift of the hadron spectrum. We also show that coupled channels reduce the breaking of chiral symmetry, with the same Feynman diagrams that appear in the coupling of a scalar meson to a pair of pseudoscalar mesons. With a Lattice QCD inspired quark-quark interaction, we find that the groundstate I=0, 3P0 quark antiquark meson is the f0(980) with a partial decay width of 40MeV. We also find a 30% reduction of the chiral condensate due to coupled channels.
