The color force acting on a quark in the pion and nucleon
Wei-Yang Liu, Edward Shuryak, Ismail Zahed
In the Operator Product Expansion (OPE) of hard scattering amplitudes, the twist-3 operators describe local colored Lorentz forces acting on a quark, thereby providing a measure of…
Tomography of the Rho meson in the QCD Instanton Vacuum: Transverse Momentum Dependent Parton Distribution Functions
Wei-Yang Liu, Ismail Zahed
We analyse the rho meson unpolarized and polarized transverse momentum dependent parton distribution functions (TMDPDFs) in the instanton liquid model (ILM). The corresponding TMDs…
Tomography of Pions and Kaons in the QCD Vacuum: Transverse Momentum Dependent Parton Distribution Functions
Wei-Yang Liu, Ismail Zahed
We evaluate the pion and kaon transverse momentum dependent parton distribution functions (TMDPDFs) in the instanton liquid model (ILM), a model of the QCD vacuum at low resolution…
Collins-Soper Kernel in the QCD Instanton Vacuum
Wei-Yang Liu, Ismail Zahed, Yong Zhao
We outline a general framework for evaluating the non-perturbative soft functions in the QCD instanton vacuum. In particular, from the soft function we derive the Collins-Soper (CS…
Nucleon electric dipole form factor in QCD vacuum
Wei-Yang Liu, Ismail Zahed
In the QCD vacuum, the nucleon form factors receive contributions from the underlying ensemble of topological pseudoparticles, which are sensitive to a finite vacuum angle . We…
Generic framework for non-perturbative QCD in light hadrons
Wei-Yang Liu
In this paper, we review several topological aspects of the QCD vacuum and recent progress on this quantitative unifying framework for the low-lying hadron physics rooted in QCD by…
