Abstract

The unpolarized spin-flip isoscalar generalized parton distribution function (E{sup u}+E{sup d})(x,{xi},t) is studied in the large-N{sub c} limit at a low normalization point in the framework of the chiral quark-soliton model. This is the first study of generalized parton distribution functions in this model, which appear only at the subleading order in the large-N{sub c} limit. Particular emphasis is put therefore on the demonstration of the theoretical consistency of the approach. The forward limit of (E{sup u}+E{sup d})(x,{xi},t) of which only the first moment-the anomalous isoscalar magnetic moment of the nucleon-is known phenomenologically, is computed numerically. Observables sensitive to (E{sup u}+E{sup d})(x,{xi},t) are discussed.

Generalized parton distribution functions and the nucleon spin sum rules in the chiral quark soliton model

Journal Article Wakamatsu, M ; Tsujimoto, H - Physical Review. D, Particles Fields

The theoretical predictions are given for the forward limit of the unpolarized spin-flip isovector generalized parton distribution function (E{sup u}-E{sup d})(x,{xi},t) within the framework of the chiral quark soliton model, with full inclusion of the polarization of Dirac sea quarks. We observe that [(H{sup u}-H{sup d})+(E{sup u}-E{sup d})](x,0,0) has a sharp peak around x=0, which we interpret as a signal of the importance of the pionic qq excitation with large spatial extension in the transverse direction. Another interesting indication given by the predicted distribution in combination with Ji's angular momentum sum rule is that the d quark carries more angularmore »« less

Tensor charges and form factors of SU(3) baryons in the self-consistent SU(3) chiral quark-soliton model

Journal Article Ledwig, Tim ; Silva, Antonio ; Centro de Fisica Computacional ; ... - Physical Review. D, Particles Fields

We investigate the tensor form factors of the baryon octet within the framework of the chiral quark-soliton model, emphasizing those of the nucleon, taking linear 1/N{sub c} rotational as well as linear m{sub s} corrections into account, and applying the symmetry-conserving quantization. We explicitly calculate the tensor form factors H{sub T}{sup q}(Q{sup 2}) corresponding to the generalized parton distributions H{sub T}(x,{xi},t). The tensor form factors are obtained for the momentum transfer up to Q{sup 2{<=}}1 GeV{sup 2} and at a renormalization scale of 0.36 GeV{sup 2}. We find for the tensor charges {delta}u=1.08, {delta}d=-0.32, and {delta}s=-0.01 and discuss their physicalmore »« less

Spin-flavor structure of chiral-odd generalized parton distributions in the large- $N_{c}$ limit

Journal Article Schweitzer, P. ; Weiss, C. - Physical Review C

We study the spin-flavor structure of the nucleon's chiral-odd generalized parton distributions (transversity GPDs) in the large-N _c limit of QCD. In contrast to the chiral-even case, only three combinations of the four chiral-odd GPDs are nonzero in the leading order of the 1/N _c expansion: E-bar _T = E _T+2H-tilde _T, H _T, and E-tilde _T. The degeneracy is explained by the absence of spin-orbit interactions correlating the transverse momentum transfer with the transverse quark spin. It can also be deduced from the natural N _c scaling of the quark-nucleon helicity amplitudes associated with the GPDs. In the GPDmore »« less

Dual parametrization of the proton generalized parton distribution functions H and E, and description of the deeply virtual Compton scattering cross sections and asymmetries

Journal Article Guzey, V ; Teckentrup, T - Physical Review. D, Particles Fields

We develop the minimal model of a new leading order parametrization of generalized parton distributions (GPDs) introduced by Polyakov and Shuvaev. The model for GPDs H and E is formulated in terms of the forward quark distributions, the Gegenbauer moments of the D-term, and the forward limit of the GPD E. The model is designed primarily for small and medium-size values of x{sub B}, x{sub B}{<=}0.2. We examine two different models of the t dependence of the GPDs: the factorized exponential model and the nonfactorized Regge-motivated model. Using our model, we successfully described the deeply virtual Compton scattering (DVCS) crossmore »« less

Chiral-odd generalized parton distributions, transversity decomposition of angular momentum, and tensor charges of the nucleon

Journal Article Wakamatsu, M - Physical Review. D, Particles Fields

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), with particular emphasis on the transversity decomposition of nucleon angular momentum proposed by Burkardt. A strong correlation between quark spin and orbital angular momentum inside the nucleon is manifest in the derived second moment sum rule within the CQSM, thereby providing an additional support to the qualitative connection between chiral-odd GPDs and Boer-Mulders effects. We further confirm isoscalar dominance of the corresponding first moment sum rule, which indicates that the Boer-Mulders functions for themore »« less
