Title: Sum rule for the polarized structure function g{sub 2} corresponding to the moment at n=0

Abstract

In the small Q{sup 2} region, the sum rule for the polarized structure function g{sub 2} corresponding to the moment at n=0 is derived. This sum rule shows that there is a tight connection among the resonances, the elastic and the continuum in the g{sub 2}. Further, the Born term contribution in this sum rule is proportional to Q{sup 2} and very small compared with that in the corresponding sum rule for the polarized structure function g{sub 1}. However, the Born term contribution divided by Q{sup 2}/2 which also appears in the Schwinger sum rule for the g{sub 2} corresponding to the moment at n=1 has a very similar behavior with that in the sum rule for the g{sub 1} corresponding to the moment at n=0.

  • The sum rules for the spin dependent structure function g{sub 1}{sup ab} in the null-plane formalism corresponding to the moment at n = 0 has been transformed to the sum rule which relates the g{sub 1}{sup ab} with the cross section of the isovector photon or the real photon. Based on these sum rules, we argue that there is a deep connection among the elastic, the resonance, and the non-resonant contributions, and that it explains why the sign of the generalized Gerasimov-Drell-Hern sum changes at very small Q2.
  • The sum rule for the structure function g{sub 1}{sup p} which is related to the cross section of photoproduction is used to show that a sign change of the integral corresponding to the appropriately defined moment at n=0 where the integral is cut at the point x=x{sub c}(Q{sup 2}) occurs at very small Q{sup 2} near Q{sup 2}{approx}0.09 (GeV/c){sup 2} and x{sub c}{approx}0.024. This fact shows that the origin of the sign difference between the Ellis-Jaffe sum rule and the Drell-Hearn-Gerasimov sum rule lies in the rapid change of the elastic contribution at low Q{sup 2} which is compensated bymore » the inelastic contribution to satisfy the sum rule at n=0. Hence it occurs at very small Q{sup 2}.« less
  • We present the next-to-next-to-leading order ({alpha}{alpha}{sub s}{sup 2}) corrections to the first moment of the polarized virtual photon structure function g{sub 1}{sup {gamma}}(x,Q{sup 2},P{sup 2}) in the kinematical region {lambda}{sup 2}<<P{sup 2}<<Q{sup 2}, where -Q{sup 2}(-P{sup 2}) is the mass squared of the probe (target) photon and {lambda} is the QCD scale parameter. In order to evaluate the three-loop-level photon matrix element of the flavor singlet axial current, we resort to the Adler-Bardeen theorem for the axial anomaly and we calculate in effect the two-loop diagrams for the photon matrix element of the gluon operator. The {alpha}{alpha}{sub s}{sup 2} correctionsmore » are found to be about 3% of the sum of the leading order ({alpha}) and the next-to-leading order ({alpha}{alpha}{sub s}) contributions, when Q{sup 2}=30{approx}100 GeV{sup 2} and P{sup 2}=3 GeV{sup 2}, and the number of active quark flavors n{sub f} is three to five.« less
  • We consider the effect of the transitions n{r_arrow}{Delta}{sup 0} and p{r_arrow}{Delta}{sup +} in deep inelastic scattering on polarized {sup 3}He on the extraction of the neutron spin structure function g{sub 1}{sup n}(x,Q{sup 2}). Making the natural assumption that these transitions are the dominant non-nucleonic contributions to the renormalization of the axial vector coupling constant in the A=3 system, we find that the effect of {Delta} increases g{sub 1}{sup n}(x,Q{sup 2}) by 15{minus}30% in the range 0.2{le}x{le}0.6, where our considerations are applicable and the data for g{sub 1}{sup n}(x,Q{sup 2}) exist.
