A note on the QCD evolution of generalized form factors

Understand

Generalized form factors of hadrons are objects appearing in moments of the generalized parton distributions.

• Their leading-order DGLAP-ERBL QCD evolution is exceedingly simple and the solution is given in terms of matrix triangular structures of linear equations where the coefficients are the evolution ratios.
• We point out that this solution has a practical importance in analyses where the generalized form factors are basic objects, e.g., the lattice-gauge studies or models.
• It also displays general features of their evolution.
