80. Reconstructing GTMDs in terms of GPDs and TMDs

In this contribution, I will discuss how leading-twist generalised transverse-momentum distributions (GTMDs) can be faithfully reconstructed in terms of generalised parton distributions (GPDs) and transverse-momentum distributions (TMDs). Focusing on the operator definition of GTMDs, I will present the computation of the one-loop corrections to the matching functions on GPDs, also deriving...

Within the Euclidean path-integral formalism of lattice quantum chromodynamics, connected quark and disconnected sea quarks appear as distinct contributions to lattice calculations of the electromagnetic form factors (FFs). Analogous partitioning exists for combined lattice and phenomenological extractions of parton distribution functions (PDFs). In this work, we show that lattice calculations...

42. Exclusive dijet electroproduction as a probe of GPDs

The talk will be based on arXiv:2603.09686 [hep-ph].
We summarize the formalism for calculating the exclusive dijet production in $e p \to e^{\prime} jj p$ in collinear QCD factorization, using generalized parton distributions (GPDs) as the soft hadronic input modeled in the double distribution (DD) approach. We include all leading-order contributions coming from light sea and valence quark...
