Charm Antiquark and Charm Quark in the Nucleon
Xiaotong Song
We estimate the intrinsic charm contributions to the quark flavor and spin observables of the nucleon in the SU(4) quark meson fluctuation model. In this model, the charm or antich…
Intrinsic Charm Flavor and Helicity Content in the Proton
Xiaotong Song
Contributions to the quark flavor and spin observables from the intrinsic charm in the proton are discussed in the SU(4) quark meson fluctuation model. Our results suggest that the…
Quark Orbital Angular Momentum in the Baryon
Xiaotong Song
Analytical and numerical results, for the orbital and spin content carried by different quark flavors in the baryons, are given in the chiral quark model with symmetry breaking. Th…
Modified Wandzura-Wilczek Relation with the Nachtmann Variable
X. Song
If one retains M^2/Q^2 terms in the kinematics, the Nachtmann variable ξseems to be more appropriate to describe deep inelastic lepton-nucleon scattering. Up to the first power of…
One-Loop Factorization of the Nucleon g_2-Structure Function in the Non-Singlet Case
Xiangdong Ji, Wei Lu, Jonathan Osborne +1
We consider the one-loop factorization of the simplest twist-three process: inclusive deep-inelastic scattering of longitudinally-polarized leptons on a transversely-polarized nucl…
Baryon Magnetic Moments and Quark Orbital Motion in the Chiral Quark Model
Xiaotong Song
Using the unified scheme for describing both quark spin and orbital angular momenta in the chiral quark model developed in the previous work, the magnetic moments of octet and decu…
