Chiral Corrections to Matrix Elements of Twist-2 Operators

Creators

Description

We compute the leading non-analytic contributions of the form mq Log(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
