Quark and gluon tomography of the helium-4 nucleus
V. Martínez-Fernández, B. Pire, P. Sznajder +1
QCD collinear factorization allows coherent hard exclusive reactions to reveal the quark-gluon structure of light nuclei, enabling their 3D tomography. We study elastic form factor…
Complete 1-loop study of exclusive and photoproduction with full GPD evolution
Chris Flett, Jean-Philippe Lansberg, Saad Nabeebaccus +3
We discuss the exclusive photoproduction of a heavy vector quarkonium, namely and at 1-loop in . In collinear factorisation (CF), the amplitude for such a process is…
Nucleon tomography and total angular momentum of valence quarks from synergy between lattice QCD and elastic scattering data
Krzysztof Cichy, Martha Constantinou, Paweł Sznajder +1
We present an exploratory work on integrating lattice-QCD results with experimental data for elastic scattering. Within the framework of generalized parton distributions (GPDs), th…
