Computing Light-Front Wave Functions Without Light-Front Quantization: A Large-Momentum Effective Theory Approach

  title={Computing Light-Front Wave Functions Without Light-Front Quantization: A Large-Momentum Effective Theory Approach},
  author={X. Ji and Yizhuang Liu},
Light-front wave functions play a fundamental role in the light-front quantization approach to QCD and hadron structure. However, a naive implementation of the light-front quantization suffers from various subtleties including the well-known zero-mode problem, the associated rapidity divergences which mixes ultra-violet divergences with infrared physics, as well as breaking of spatial rotational symmetry. We advocate that the light-front quantization should be viewed as an effective theory in… Expand

Quantum chromodynamics and other field theories on the light cone
Abstract In recent years light-cone quantization of quantum field theory has emerged as a promising method for solving problems in the strong coupling regime. The approach has a number of uniqueExpand

Solving two-dimensional phi4 theory by discretized light-front quantization.
It is found that finite-mass renormalization prevents the phase transition by restricting the theory to the weak-coupling region and estimate of the critical coupling for which the mass gap vanishes is obtained. Expand
Parton physics from large-momentum effective field theory
Parton physics, when formulated as light-front correlations, are difficult to study non-perturbatively, despite the promise of light-front quantization. Recently an alternative approach to partonsExpand

Nonperturbative QCD: A weak-coupling treatment on the light front.
The weak-coupling approach potentially reconciles the simplicity of the Constituent Quark Model with the complexities of QuantumChromodynamics, and the necessity of formulating the dynamic QCD in light-front coordinates and of dealing with the complications of renormalization which such a formulationentails.
