Inclusive and exclusive inelastic processes in QCD2021.11.17 12:17 - admin
For a long time, it Was believed that fundamental constituents of atoms were electrons and nucleons until experiments conducted in the 1960 s at Standford Linear Accelerator Center (SLAC) proved the existence of internal dynamics in the nucleons. With QCD as the fundamental theory for hadrons, we can describe hadronic structure via correlations between some degrees of freedom that we call quarks and gluons, collectively partons. The non-elementary nature of hadrons makes these correlators perturbatively unsolvable so we can only measure or model them. In this seminar, I review and compare 2 of these correlators/distributions, namely PDF and GPD, and discuss how to study phenomenology of a particular exclusive inelastic process (double deeply virtual Compton scattering) in order to extract information on the partonic distributions beyond leading-order accuracy.
