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) $H^{u + d}$ and $E^{u + d}$ 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…

Generalized parton distributions of the nucleon in the chiral quark soliton model: Sum over all quark states at nonzero skewness and momentum transfer

Josuke Minamiguchi

We compute the combinations $E_{M} = H^{u + d} + E^{u + d}$ and $H_{E} = H^{u - d} + t E^{u - d} / (4 M_{N}^{2})$ of unpolarized generalized parton distributions (GPDs) of the nucleon in the chiral quark soli…

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…
