Inverse Problem Approach for Non-Perturbative QCD: Applications
Yong Zheng, Ao-Sheng Xiong, Fu-Sheng Yu +1
In arXiv:2211.13753 we proposed a novel theoretical approach for non-perturbative QCD, named the inverse problem approach. It extracts non-perturbative quantities by solving a disp…

Ill-Posedness in Limited Discrete Fourier Inversion and Regularization for Quasi Distributions in LaMET
Ao-Sheng Xiong, Jun Hua, Ting Wei +3
We systematically investigated the limited inverse discrete Fourier transform of the quasi distributions from the perspective of inverse problem theory. This transformation satisfi…

Inverse Problem Approach for Non-Perturbative QCD: Theoretical Foundation
Ao-Sheng Xiong, Fu-Sheng Yu, Yong Zheng +1
A novel theoretical framework, the inverse problem approach, is proposed to calculate non-perturbative quantities in quantum chromodynamics (QCD). Based on the dispersion relation…
