Broken colour symmetry and liberated quarks
Abstract
We present and discuss a quark model of hadrons, in which local SU(3) gauge symmetry is completely broken and yet asymptotic freedom is presented. There is no infrared slavery in this model, and isolated quarks are free to exist. Colour becomes a global symmetry which is only approximate under SU(3) but nearly exact under SU(2) × U(1), as far as the usual hadron spectroscopy is concerned.
