چکیده
Because the chiral-odd structure function h 1 will be measured in the polarized Drell-Yan process, it is important to predict the behavior of h 1 before the measurement. In order to study the Q 2 evolution of h 1 , w e discuss one and two l o o p anomalous dimensions which are calculated in the Feynman gauge and minimal subtraction scheme.

Chiral-odd structure function h 1 is expected to be measured in polarized Drell-Yan process. We calculate two-loop anomalous dimensions for h 1 in the minimal subtraction scheme. Dimensional regularization and Feynman gauge are used for calculating the two-loop contributions. Our results are important in studying Q 2 dependence of h 1 .

Employing the operator algebra of the conformal group and the conformal Ward identities, we derive the constraints for the anomalies of dilatation and special conformal transformations of the local twist-2 operators in Quantum Chromodynamics. We calculate these anomalies in the leading order of perturbation theory in the minimal subtraction scheme. From the conformal consistency relation we der...
