dc.descriptionLight-front quantum chromodynamics may lead to an accurate constituent approximation for the low-energy properties of hadrons. This requires a cutoff that violates explicit gauge invariance and Lorentz covariance, leading to the calculation of a renormalized QCD hamiltonian using a similarity renormalization group. Renormalization repairs broken symmetries, and in light-front field theory it moves dynamical effects that usually require large numbers of partons to few-body effective interactions. This has been shown to work in QED through dominant contributions to the Lamb shift. In QCD logarithmic confinement arises at second order, and initial bound state calculations produce reasonable results.
