On the Twist 2 and Twist 3 Contributions to the Spin-dependent Electroweak Structure Functions
The twist 2 and twist 3 contributions of the polarized deep-inelastic structure functions are calculated both for neutral and charged current interactions using the operator product expansion in lowest order in QCD. The relations between the different structure functions are determined. New integral relations are derived between the twist 2 contributions of the structure functions g3(x,Q ) and ...
متن کاملHigher Twist Contributions to Deep-Inelastic Structure Functions
In wide kinematic regions the deeply inelastic structure functions can be described by their leading twist contributions within Quantum Chromodynamics (QCD). Higher twist corrections [1] emerge both in the region of large [2,3] and small values [4,5] of the Bjorken variable x. The leading twist sector, both for unpolarized and polarized deeply inelastic scattering, is well explored within pertu...
متن کاملIntegral Relations for Twist 2 and Twist 3 Contributions to Polarized Structure Functions
We discuss the relations between the twist 2 and twist 3 contributions to polarized deep-inelastic scattering structure functions both for neutral and charged current interactions which are predicted by the operator product expansion in lowest order in QCD. INTRODUCTION In the case of polarized deep inelastic scattering the cross sections depend on (up to) three unpolarized Fi(x,Q 2)3i=1 and fi...
متن کاملTarget Mass Corrections to the Spin-dependent Structure Functions
At the energies at which most data in polarized deep-inelastic scattering have been taken the ratio M/Q, where M is the mass of the nucleon, is not negligible. The target mass corrections should be taken into account to analyze the Q dependence of structure functions at low Q and to extract information of dynamical higher twist effects at moderate energies. We calculated the target mass correct...
متن کاملHigher-twist Corrections to Nucleon Structure Functions from Lattice Qcd *
A genuinely non-perturbative evaluation of higher-twist contributions to the structure functions of the nucleon, with all mixing effects and renormalon ambiguities taken care of, is presented. Higher-twist corrections turn out to be significant at moderate values of q 2 .
