Revealing the nucleon structure through exclusive meson production
Hadron structure is investigated through the study of hard exclusive processes, in particular the exclusive photoproduction of mesons on a nucleon. At high energies, these processes can be described within a perturbative framework, allowing for the factorization of short- and long-distance dynamics. This, in turn, enables access to hadron structure in terms of distribution amplitudes (DAs) and generalized parton distributions (GPDs). Unlike parton distribution functions encountered in deeply inelastic scattering, which provide a one-dimensional view of partons, GPDs offer the possibility of a three-dimensional (3D) picture of hadrons. Photon-meson (γM) photoproduction (γ N → γ M N′) is studied as a promising channel for GPD analyses and is potentially measurable at current and future facilities. The present work focuses on the production of pseudoscalar mesons, with particular attention to gluon contributions in the description of flavour-singlet mesons (η′).
Seminar će se održati u petak 11. srpnja 2025. godine u 13:00 sati u predavaonici F-201 na Fizičkom odsjeku Prirodoslovno-matematičkog fakulteta.
Pozivaju se studenti doktorskog studija Fizike, smjer Fizika elementarnih čestica da prisustvuju seminaru, ako nisu spriječeni.
