“…Note that within our approach we can estimate the first moment of g 2 . As can be seen from the table 1 the sign of the first moment of g 2 calculated within our scheme 1 0 dxg 2 < 0, is in agreement with the result of SLAC experiment [12].…”

The one-loop NLO radiative corrections (RC) to the observables in polarized DIS using assumption that a quark is an essential massive particle are considered. If compared with classical QCD formulae the obtained results are identical for the unpolarized and different for polarized sum rules, that can be explained as the influence of the finite quark mass effects on NLO QCD corrections. The explicit expression for one-loop NLO QCD contribution to the structure function g2 is presented.

The target mass corrections are calculated for all structure functions of neutral and charged current deep inelastic scattering in lowest order in the coupling constant. Representations of the correction to the twist-2 and twist-3 contributions are derived both in Mellin-n and x-space. The impact of the target mass corrections on the general relations between the twist-2 and twist-3 parts of the structure functions is studied and three new relations between the twist-3 contributions are derived.

“…In the present work we have limited ourselves to give predictions for D-Y related observables in some kinematic regions accessible to RHIC, but the model can be straightforwardly applied to other experimental conditions and to other kind of processes as well. In particular, the observed enhancement of the transverse polarization with respect to the longitudinal one may have some impact in the extraction of the twist-3 contribution to the spin structure function g 2 from DIS experiments [30] (see also [31]).…”

Probing relativistic spin effects in the nucleon by means of Drell-Yan processes

2000

View full text Add to dashboard Cite

Significant differences between transverse and longitudinal polarized parton distributions are found at low energies within a light-front covariant quark model of the nucleon. These differences are due to relativistic spin effects introduced by the Melosh rotations and survive evolution to higher Q 2 scales. A specific observable related to double-spin asymmetries in lepton pair production in polarized hadron-hadron collisions is defined. The possibility of assessing the relevance of these relativistic spin effects in future experiments at RHIC and HERA-N is discussed.
