Gauge- and frame-independent decomposition of nucleon spin
M. Wakamatsu
In a recent paper, we have shown that the way of gauge-invariant decomposition of the nucleon spin is not necessarily unique, but there still exists a preferable decomposition from…
The role of orbital angular momentum in the proton spin
M. Wakamatsu
The orbital angular momenta and of up and down quarks in the proton are estimated as functions of the energy scale as model-independently as possible, on the basis of J…
Transverse momentum distributions of quarks in the nucleon from the Chiral Quark Soliton Model
M. Wakamatsu
We report the first calculation of the simplest but most fundamental transverse momentum dependent (TMD) distribution of quarks in the nucleon, i.e. the time-reversal-even unpolari…
Chiral-odd generalized parton distributions, transversity decomposition of angular momentum, and tensor charges of the nucleon
M. Wakamatsu
The forward limit of the chiral-odd generalized parton distributions (GPDs) and their lower moments are investigated within the framework of the chiral quark soliton model (CQSM),…
The nonperturbative origin of delta-function singularity in the chirally-odd twist-3 distribution function e(x)
M. Wakamatsu, Y. Ohnishi
We analytically prove that the existence of the delta-function singularity in the chirally-odd twist-3 distribution of the nucleon is inseparably connected with the nonvanis…
A chiral theory of strange sea distributions in the nucleon
M. Wakamatsu
Theoretical predictions are given for the strange sea distributions in the nucleon based on the flavor SU(3) chiral quark soliton model, with emphasis upon the asymmetry of quark a…
