Abstract: We study the cross section for one-particle inclusive deep inelastic scattering off the nucleon for low transverse momentum of the detected hadron. We decompose the cross section in termsâ€¦ (More)

The general parameterization of the quark-quark correlation function for a spin-1 2 hadron is considered. The presence of the Wilson line ensuring color gauge invariance of the correlator inducesâ€¦ (More)

The Collins fragmentation function is extracted from HERMES data on azimuthal single spin asymmetries in semi-inclusive deeply inelastic scattering, and BELLE data on azimuthal asymmetries inâ€¦ (More)

Polarized antiprotons, produced by spin filtering with an internal polarized gas target, provide access to a wealth of singleâ€“ and doubleâ€“spin observables, thereby opening a new window to physicsâ€¦ (More)

We outline in detail the properties of generalized parton distributions (GPDs), which contain new information on the structure of hadrons and which enter the description of hard exclusive reactions.â€¦ (More)

The 1/Ncâ€“expansion of QCD suggests large flavor asymmetries of the polarized antiquark distributions in the nucleon. This is confirmed by model calculations in the largeâ€“Nc limit (chiralâ€¦ (More)

We investigate the magnetic moments of the SU(3) octet baryons in the framework of the SU (3) semibosonized Nambuâ€“Jonaâ€“Lasinio model. The ro-tational 1/N c corrections and strange quark mass inâ€¦ (More)

We compute the quark and antiquark transversity distributions in the nucleon at a low normalization point (Î¼â‰ˆ600MeV) in the largeâ€“Nc limit, where the nucleon can be described as a soliton of anâ€¦ (More)

We study the off-forward quark distributions (OFQDâ€™s) in the chiral quark-soliton model of the nucleon. This model is based on the large-Nc picture of the nucleon as a soliton of the effective chiralâ€¦ (More)

The Sivers function is extracted from HERMES data on single spin asymmetries in semi-inclusive deeply inelastic scattering. Our analysis use a simple Gaussian model for the distribution of transverseâ€¦ (More)
