Chiral Corrections to Matrix Elements of Twist-2 Operators
Daniel Arndt🇺🇸 · Martin J. Savage🇺🇸
Abstract
We compute the leading non-analytic 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.
