WebSep 17, 2015 · 123. Thinking aloud. Most descriptions of chiral symmetry breaking nowadays present it as something happening in QCD. But it was defined well before of the quark theory, and then it was something related to isospin symmetry. It is a bit puzzling because it seems as if pion mass were originated from two different forces. 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.
