Nucleon to Delta electromagnetic transition in the Dyson-Schwinger approach
Gernot Eichmann, Diana Nicmorus
We study the N-Delta-gamma transition in the Dyson-Schwinger approach. The nucleon and Delta baryons are treated as quark-diquark bound states, where the ingredients of the electro…
Baryons in and beyond the quark-diquark model
G. Eichmann, R. Alkofer, C. S. Fischer +2
We examine the nucleon's electromagnetic form factors in a Poincare-covariant Faddeev framework. The three-quark core contributions to the form factors are obtained by employing a…
Delta properties in the rainbow-ladder truncation of Dyson-Schwinger equations
D. Nicmorus, G. Eichmann, A. Krassnigg +1
We present a calculation of the three-quark core contribution to nucleon and Delta-baryon masses and Delta electromagnetic form factors in a Poincare-covariant Faddeev approach. A…
Delta and Omega electromagnetic form factors in a Dyson-Schwinger/Bethe-Salpeter approach
Diana Nicmorus, Gernot Eichmann, Reinhard Alkofer
We investigate the electromagnetic form factors of the Delta and the Omega baryons within the Poincare-covariant framework of Dyson-Schwinger and Bethe-Salpeter equations. The thre…
Review on dynamically generated resonances
E. Oset, R. Molina, D. Nicmorus +10
We present recent results on the vector meson-vector meson and vector meson-baryon interaction using a unitary approach based on the hidden-gauge Lagrangians. For the vector-vector…
Hadron properties from QCD bound-state equations: A status report
Reinhard Alkofer, Gernot Eichmann, Andreas Krassnigg +1
Employing an approach based on the Green functions of Landau-gauge QCD, some selected results from a calculation of meson and baryon properties are presented. A rainbow-ladder trun…
Covariant solution of the three-quark problem in quantum field theory: the nucleon
G. Eichmann, R. Alkofer, A. Krassnigg +1
We provide details on a recent solution of the nucleon's covariant Faddeev equation in an explicit three-quark approach. The full Poincare-covariant structure of the three-quark am…
Nucleon mass from a covariant three-quark Faddeev equation
G. Eichmann, R. Alkofer, A. Krassnigg +1
We report the first study of the nucleon where the full Poincare-covariant structure of the three-quark amplitude is implemented in the Faddeev equation. We employ an interaction k…
Dynamically generated resonances
E. Oset, A. Ramos, S. Sarkar +8
In this talk I report on recent work related to the dynamical generation of baryonic resonances, some made up from pseudoscalar meson-baryon, others from vector meson-baryon and a…
Dynamically generated resonances from vector meson-vector meson interaction based on a hidden-gauge unitary approach
L. S. Geng, E. Oset, R. Molina +1
We present a recent study of vector meson-vector meson interaction using a unitary approach based on the hidden-gauge Lagrangians. We find that 11 states get dynamically generated,…

E. Oset, L. S. Geng, D. Gamermann +7
In this talk I review recent advances on the structure of the meson and baryon resonances which can be dynamically generated from the interaction of mesons or mesons and baryons. P…

The ρρinteraction in the hidden gauge formalism and the f_0(1370) and f_2(1270) resonances
R. Molina, D. Nicmorus, E. Oset
We have studied the interaction of vectors mesons within the hidden gauge formalism and applied it to the particular case of the interaction. We find a strong attraction in th…
