摘要：

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