چکیده
We calculate the unpolarized and polarized three–loop anomalous dimensions splitting functions PNS+,PNS? PNSs in QCD MS? scheme by using traditional method of space–like off shell massless operator matrix elements. This is a gauge–dependent framework. For first time we also PNS±,tr for transversity directly. compare our results to literature.

Two–Loop Massive Operator Matrix Elements for Unpolarized Heavy Flavor Production to O(ǫ)
We calculate the O(αs) massive operator matrix elements for the twist–2 operators, which contribute to the heavy flavor Wilson coefficients in unpolarized deeply inelastic scattering in the region Q2 ≫ m2, up to the O(ε) contributions. These terms contribute through the renormalization of the O(αs) heavy flavor Wilson coefficients of the structure function F2(x,Q 2). The calculation has been pe...
متن کاملQcd Sum Rules and the Determination of Leading Twist Non–singlet Operator Matrix Elements
We use QCD sum rules to determine directly the leading–twist non–singlet operator matrix elements based on calculations of three–point correlator functions in configuration space. We find a different result from that obtained by integrating the structure functions’ expressions obtained by Belyaev and Ioffe based on calculations of four–point correlators in momentum space. The origin of this dis...

متن کاملTwist-2 Light-Ray Operators: Anomalous Dimensions and Evolution Equations1
The non–singlet and singlet anomalous dimensions of the twist–2 light–ray operators for unpolarized and polarized deep inelastic scattering are calculated in O(αs). We apply these results for the derivation of evolution equations for partition functions, structure functions, and wave functions which are defined as Fourier transforms of the matrix elements of the light-ray operators. Special cas...
متن کاملDetermination of Leading Twist Non–singlet Operator Matrix Elements by Qcd Sum Rules
We use QCD sum rules to determine the twist-two non–singlet operator matrix elements and fixed x structure functions paying particular regard to the estimate of the errors. Particularly for the matrix element determination, we find large uncertainties due to radiative and higher dimension contributions. We consider the origin of these large corrections and comment on their consequences for othe...
