چکیده

On the basis of the target mass corrections to structure functions of deep-inelastic scattering of leptons, we evaluate effective nucleon mass that turns out to be twice M nucl. for deep-inelastic scattering on the nucleus target and equals M nucl. for the hydrogen target.

The negative-parity baryons are studied by a novel approach in the QCD sum rule. It is found that the parity of the ground-state nucleon is determined by the sign of the quark condensate. We predict the mass of negative-parity nucleon.

We study the effective weak chiral Lagrangian within the framework of the instanton vacuum. We incorporate the ∆S = 1, 2 effective weak Hamiltonian into the effective low-energy QCD partition function defining the chiral symmetric quark-Goldstone boson interactions with the momentum-dependent dynamical quark mass. Employing the derivative expansion, we derive the corresponding weak effective La...

QCD suggests that gluons in the nucleon play an important role in so-called " the proton spin problem ". In this talk, the behavior of the polarized gluon distribution in the nucleon is discussed by using the positivity condition of distribution functions together with the unpolarized and polarized experimental data.

For J/Ψ → ¯ ppπ 0 and ¯ ppπ + π − , the π 0 p and pπ + π − systems are limited to be pure isospin 1/2 due to isospin conservation. This is a big advantage in studying N * resonances from J/Ψ decays, compared with πN and γN experiments. The process J/Ψ → ¯ pN * or p ¯ N * provides a new way to probe the internal structure of the N * resonances. Here we report a quark model calculation for J/Ψ → ...
