2D Gauge Field Theory

الأصل · EN

We show from the action integral that under the assumption of longitudinal dominance and transverse confinement, QCD4 in (3+1) dimensional space-time can be approximately compactified into QCD2 in (1+1) dimensional space-time. In such a process, we find the relation between the coupling constant g(2D) in QCD2 and the coupling constant g(4D) in QCD4. We also show that quarks and gluons in QCD2 acquire masses as a result of the compactification.
