چکیده

We present the recent JLab measurements on moments of spin structure functions at intermediate and low Q2. The Bjorken sum and Burkhardt-Cottingham sum on the neutron are presented. The later appears to hold. Higher moments (generalized spin polarizabilities and dn 2) are shown and compared to chiral perturbation theory and lattice QCD respectively.

Recent precision spin-structure data from Jefferson Lab have significantly advanced our knowledge of nucleon structure at low Q2. Results on the neutron spin sum rules and polarizabilities in the low to intermediate Q2 region are presented. The Burkhardt-Cuttingham Sum Rule was verified within experimental uncertainties. When comparing with theoretical calculations, results on spin polarizabili...

Jefferson Lab experiment E01-012 measured the 3He spin-structure functions and virtual photon asymmetries in the resonance region in the momentum transfer range 1.0<Q2<4.0 (GeV/c)2. Our data, when compared with existing deep inelastic scattering data, were used to test quark-hadron duality in g1 and A1 for 3He and the neutron. In addition, preliminary results on the 3He spin-structure function ...

روش خودسازگار در محاسبه نسبت با استفاده از تابع ساختار و نسبت EMC هسته‌های He3 و H3

By using the convolution formalism which consists of Fermi motion and binding effect, we investigate the deep inelastic electron scattering from A=3 mirror in the deep-valence region. The initial valence quark input is taken from the GRVs (Gluck, Reya and Vogt) fitting procedure and the next-to-leading order QCD evolution on FP2 (x,Q2) which gives very good fit to the available data in the (x,Q...

Generalized Sum Rules for Spin-Dependent Structure Functions of the Nucleon

The Drell-Hearn-Gerasimov and Bjorken sum rules are special examples of dispersive sum rules for the spin-dependent structure function G1(ν,Q 2) at Q2 = 0 and ∞. We generalize these sum rules through studying the virtualphoton Compton amplitudes S1(ν,Q 2) and S2(ν,Q 2). At small Q2, we calculate the Compton amplitudes at leading-order in chiral perturbation theory; the resulting sum rules can b...
