Generalized parton distributions of the nucleon in the chiral quark soliton model II: Chiral anomaly mediation in the polarized GPDs

Josuke Minamiguchi, Tomoya Uji

We calculate the polarized flavor-singlet generalized parton distributions (GPDs) and in the chiral quark soliton model at nonzero skewnes…

Proton GTMDs and Wigner Distributions in the Chiral Quark Soliton Model: Orbital Angular Momentum and Spin-Orbit Correlation with Sea Quarks

Josuke Minamiguchi, Tomoya Uji

We calculate the leading-twist vector and axial-vector quark generalized transverse-momentum-dependent distributions (GTMDs) of the proton in the chiral quark soliton model, includ…

Energy-momentum tensor at small from gravitational transverse-momentum distributions

Tomoya Uji

We investigate the momentum-space mechanical properties of small- gluons and sea quarks using gravitational transverse-momentum distributions (gravitational TMDs). For gluons, w…

Chiral anomaly and nucleon spin decomposition in the chiral quark soliton model

Josuke Minamiguchi, Tomoya Uji

We investigate how the chiral anomaly influences the decomposition of nucleon spin between quark spin and orbital motion. We extend the chiral quark soliton model by including a fl…

Polarized Nucleon as a Topological Dipole

Kenji Fukushima, Tomoya Uji

We show that a polarized nucleon generically carries a dipole distribution of topological charge density. This topological dipole follows robustly from the definition of the topolo…

Energy-momentum tensor form factors and spin density distribution in the nucleon calculated in a quantized Skyrme model with vector mesons

Kenji Fukushima, Tomoya Uji

We investigate energy-momentum tensor (EMT) form factors and the spatial spin density distribution in the nucleon within a framework of the quantized Skyrme model with vector meson…
