Chirality and its breaking in a new theory of hadrons
Abstract
We show that in Anisotropic Chromo-Dynamics (ACD), a new approach to the dynamics of coloured, confined quarks, the π-meson is a qq̄-bound state very close to the Nambu-Goldstone boson of a spontaneously broken chiral symmetry. We calculate the ``current'' quark masses and obtain mu(0) ~ md(0) ~ 18 MeV, and ms(0) ~ 123 Mev, in disagreement with the usual ``strong PCAC'' Ansatz.
