R. Acharya et Pn. Swamy, ASYMPTOTIC FREEDOM AND CONFINEMENT IMPLY SPONTANEOUSLY BROKEN CHIRAL-SYMMETRY IN QUANTUM CHROMODYNAMICS, Modern physics letters A, 12(22), 1997, pp. 1649-1654
We utilize Coleman's theorem and show that quantum chromodynamics base
d on asymptotic freedom and confinement must have chiral symmetry real
ized as a spontaneously broken symmetry.
