Chiral Corrections to Matrix Elements of Twist-2 Operators

Journal Article · · Nuclear Physics A
OSTI ID:838759

We compute the leading non-analytic contributions of the form m{sub q} Log(m{sub 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.
