Generalized parton distributions of pseudoscalar mesons in a relativistic Bethe-Salpeter framework

Annelies Van Dyck UGent (2008)
abstract
The research presented in this PhD dissertation is situated in the field of hadron physics. In this field, it is investigated how strongly interacting particles such as the proton and the pion are built from their elementary constituents, quarks and gluons. The laws obeyed are comprised in the standard model of particle physics. Nevertheless, the interactions between the different building blocks of matter are not entirely understood and a lot of open questions remain. Many of these questions are related to the theory of the strong interaction, which is described in quantum chromodynamics (QCD). In the energy range of hadron physics, QCD is unsolvable. Because the description of hadrons is not feasible in QCD, their inner structure is still not fully understood. One of the questions that remain to be solved, is the origin of the quantum mechanical spin of the nucleon (proton or neutron). In 1997, it was realized that an important contribution to that spin could be calculated through generalized parton distibutions (GPDs). Also for other hadrons, GPDs can be defined and measured. In this dissertation, the pion and kaon GPDs are calculated within the Lorentz covariant Bonn constituent quark model. In this model, a bound quark-antiquark state is described by the Bethe-Salpeter amplitude, which is the solution to the Bethe-Salpeter equation. The thesis describes the analytical derivation of the GPD in the Bonn model, as well as the numerically calculated results.
