New Quark Distributions and Semi-Inclusive Electroproduction on Polarized Nucleons
The quark-parton model calculation including the effects of intrinsic transverse momentum and of all six twist-two distribution functions of quarks in polarized nucleons is performed. It is demonstrated that new twist-two quark distribution functions and polarized quark fragmentation functions can be investigated in semi-inclusive DIS at leading order inQ2. The general expression for the cross-...
متن کاملFlavor asymmetry of polarized antiquark distributions and semi-inclusive DIS
The 1/Nc–expansion of QCD suggests large flavor asymmetries of the polarized antiquark distributions in the nucleon. This is confirmed by model calculations in the large–Nc limit (chiral quark–soliton model), which give sizable results for ∆ū(x)−∆d̄(x) and ∆ū(x)+∆d̄(x)−2∆s̄(x). We compute the contributions of these flavor asymmetries to the spin asymmetries in hadron production in semi-inclusive d...
متن کاملExploring the Light-Cone through Semi-Inclusive Hadronic Distributions
Light-cone dominance is established for a particular set of semi-inclusive observables in e+e− hadronic annihilation. This allows to deduce, with a certain degree of rigor, the angular distribution of hadronic energy from first principles, without invoking quark-hadron duality. ⋆ Address until August 31st, 1998. ⋆⋆ Permanent address.

15 صفحه اولSemi-inclusive DIS: Factorization
There has been considerable experimental and theoretical interest in semi-inclusive hadron production in deep inelastic scattering (SIDIS) processes. For example, by studying the polarized and unpolarized SIDIS, one will be able to identify the sea quark distribution and polarization in nucleon, and the experimental results from the HERMES collaboration have revealed nontrivial sea structure in...
