Electromagnetic baryon form factors in the Poincare-covariant Faddeev approach
Reinhard Alkofer, Gernot Eichmann, Helios Sanchis-Alepuz +1
Baryons are treated as three-quark systems using QCD degrees of freedom in Poincare-covariant bound-state equations. The quark self-energy as well as the interaction between quarks…
Octet and Decuplet masses: a covariant three-body Faddeev calculation
Helios Sanchis-Alepuz, Christian S. Fischer
We determine the baryon octet and decuplet masses as well as their wave functions in a covariant three-body Faddeev approach. We work in an approximation where irreducible three-bo…
Beyond Rainbow-Ladder in a covariant three-body Bethe-Salpeter approach: Baryons
Hèlios Sanchis-Alepuz, Stanislav D. Kubrak, Christian S. Fischer
We report on recent results of a calculation of the nucleon and delta masses in a covariant bound-state approach, where to the simple rainbow-ladder gluon-exchange interaction kern…
Pion cloud effects on baryon masses
Helios Sanchis-Alepuz, Christian S. Fischer, Stanislav Kubrak
In this work we explore the effect of pion cloud contributions to the mass of the nucleon and the delta baryon. To this end we solve a coupled system of Dyson-Schwinger equations f…
