On the anomalous dimension for the transversity distribution
  We show that a standard calculation of the splitting function for the nonsinglet structure function h_1 does not lead to the expected result. The calculation is compared to the corresponding derivation of the splitting function for the nonsinglet polarized structure function g_1. We analyze possible explanations for the unexpected result and discuss its implications. PACS: 11.10.Hi; 11.40.-q; 11.55.Ds; 13.88.+e
