Light-cone and quasi generalized parton distributions in the 't Hooft model
Yu Jia, Zhewen Mo, Xiaonu Xiong +1
We present a comprehensive study of the light-cone generalized parton distribution (GPD) and quasi-GPD of a flavor-neutral meson in the 't Hooft model, {\it i.e.}, two-dimensional…
Meson-meson scattering in two-dimensional QCD
Guo-Ying Chen, Yingsheng Huang, Yu Jia +1
We extend the formalism pioneered by Callan, Coote and Gross to investigate the meson-meson scattering within the framework of 't Hooft model, i.e., the two-dimensional QCD in the…
Near-the-origin divergence of Dirac wave functions of hydrogen and operator product expansion
Yingsheng Huang, Yu Jia, Rui Yu
There is a long-standing puzzle concerning the Coulomb solutions of the Dirac equation, i.e., what is the physics governing the weakly divergent near-the-origin behavior of the Dir…
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…
