Generalized parton distributions and gravitational form factors at large momentum transfer

Journal Article · · Journal of High Energy Physics (Online)
Within the soft collinear effective theory (SCET), we derive a factorization theorem which resums Sudakov logarithms (αs ln2( –t))n to all orders in the quark-in-quark generalized parton distribution (GPD) at large momentum transfer t, and perform a consistency check to one-loop. We show that the same Sudakov factor appears in the ‘Feynman’ contribution to the GPDs of the nucleon. Our result enables the resummation of all the large logarithms ln Q2 and ln2 t in exclusive processes with two hard scales Λ$$^{2}_{QCD}$$ ≪ |t| ≪ Q2. We also present a SCET power counting analysis of the Feynman contributions to the GPDs and show that the x-dependence of GPDs factorizes at large-t with controlled corrections. This in particular implies that any ratio of GPD moments such as the electromagnetic and gravitational form factors (GFF) is perturbatively calculable in this approximation. Furthermore, we identify a novel order αs power-law t-dependence in the GPD and the D-type GFF that will dominate over the standard order α$$^{2}_{s}$$ ‘leading twist’ asymptotic contribution in the phenomenologically relevant region of t.
