Baryon properties and glueballs from Poincare-covariant bound-state equations

Understand

In this thesis the covariant Bethe-Salpeter equation formalism is used to study some properties of ground-state baryons.

• This formalism relies on the knowledge of the interaction kernel among quarks and of the full quark propagator.
• For the interaction kernel, which is in principle a sum of infinitely many diagrams, I use the Ladder truncation.
• It amounts to reduce the interaction to a flavor-blind quark-mass independent vector-vector interaction between two quarks, mediated by a dressed gluon.
