摘要：

We compute the leading nonanalytic contributions of the form m(q) log m(q) to matrix elements of twist-2 operators in the nucleon and pion using effective field theory. Previously omitted one-loop contributions that are related to tree-level matrix elements by chiral symmetry are included. (C) 2002 Elsevier Science B.V. All rights reserved.
