# Computing light-front wave functions without light-front quantization: A large-momentum effective theory approach

@article{Ji2022ComputingLW, title={Computing light-front wave functions without light-front quantization: A large-momentum effective theory approach}, author={Xiangdong Ji and Yizhuang Liu}, journal={Physical Review D}, year={2022} }

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…
