WebChiral symmetry is a symmetry of QCD in the limit that the quark masses are set equal to zero. However, this symmetry is not manifest in the spectrum of hadron masses, even after we correct for the fact that the masses of quarks are not exactly zero. Instead, this symmetry is realized in a different way; it is said to be spontaneously broken.
