All order factorization for virtual Compton scattering at next-to-leading power

Jakob Schoenleber, Robert Szafron

We discuss all-order factorization for the virtual Compton process at next-to-leading power (NLP) in the ${\Lambda }_{\mathrm{QCD}}/Q$ and $\sqrt{-t}/Q$ expansion (twist-3), both in the double-d…
