Pentaquarks on the light front, and their mixture with baryons

Nicholas Miesch, Edward Shuryak, Ismail Zahed

In previous papers we developed the light front formulation for Hamiltonians and wave functions (WFs) for mesons and baryons, with both confinement and chiral symmetry breaking. Fo…

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…

Light S-wave pentaquarks on the light front

Fangcheng He, Edward Shuryak, Wan Wu +1

We construct an explicit basis set for pentaquark states on a regular 4-simplex, that diagonalizes the Hamiltonian for light pentaquarks with confinement on the light front (LF). T…

Pentaquarks made of light quarks and their admixture to baryons

Nicholas Miesch, Edward Shuryak, Ismail Zahed

This paper is a continuation of our studies of multiquark hadrons. The anti-symmetrization of their wavefunctions required by Fermi statistics is nontivial, as it mixes orbital, co…

D-shell mixing in light baryons and its effect on the orbital motion

Nicholas Miesch, Edward Shuryak, Ismail Zahed

The standard description of the nucleon in the non-relativistic quark model is an state without orbital motion. Yet, there are several indications from phenomenology that…

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…
