Evolving QCD
  We give an overview of the current theoretical status of proper time renormalization group flow equations applied to QCD. These equations give the evolution of coupling constants in an effective QCD Lagrangian as a function of an infra-red cut-off parameter. This parameter characterizes the resolution with which the system is looked at. Decreasing resolution transforms partonic quarks into constituent quarks and generates pion bound states. The evolution equations can also be applied to finite temperature and finite density QCD.
