Near-the-origin divergence of Klein-Gordon wave functions for hydrogen-like atoms and operator product expansion
Yingsheng Huang, Yu Jia, Rui Yu
There have been some long-standing puzzles related to the Coulomb solutions of the Klein-Gordon and Dirac equations, namely how to understand the physics underlying the weakly dive…
Deciphering the coalescence behavior of Coulomb-Schrödinger atomic wave functions from an operator product expansion
Yingsheng Huang, Yu Jia, Rui Yu
We revisit the coalescence behavior of the atomic Schrödinger wave functions from the angle of an operator product expansion (OPE) within the nonrelativistic Coulomb-Schrödinger ef…
Gauge-invariant decomposition of meson energy in two-dimensional QCD
Yu Jia, Rui Yu, Xiaonu Xiong
This work is driven by our curiosity towards some basic questions in QCD: how is the energy of a moving hadron partitioned among different gauge-invariant sectors in QCD Hamiltonia…
Partonic quasidistributions in two-dimensional QCD
Yu Jia, Shuangran Liang, Xiaonu Xiong +1
As a sequel of our preceding work [1] we carry out a comprehensive comparative study between the quasi parton distribution functions (PDFs), distribution amplitudes (DAs) and their…
