Chiral corrections to matrix elements of twist-2 operators
Abstract
We compute the leading nonanalytic contributions of the form mqlog mq 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.
