Nucleon mass and pion loops
M. B. Hecht, M. Oettel, C. D. Roberts +3
Poincare' covariant Faddeev equations for the nucleon and Delta are solved to illustrate that an internally consistent description in terms of confined-quark and nonpointlike confi…
Kaon Photoproduction in a Confining and Covariant Diquark Model
R. Alkofer, S. Ahlig, C. Fischer +1
Baryons are modeled as bound states of scalar or axialvector diquarks and a constituent quark which interact through quark exchange. This description results as an approximation to…
Form Factors of Baryons in a Confining and Covariant Diquark-Quark Model
M. Oettel, S. Ahlig, R. Alkofer +1
We treat baryons as bound states of scalar or axialvector diquarks and a constituent quark which interact through quark exchange. This description results as an approximation to th…
Current Conservation in the Covariant Quark-Diquark Model of the Nucleon
Martin Oettel, Mike Pichowsky, Lorenz von Smekal
The description of baryons as fully relativistic bound states of quark and glue reduces to an effective Bethe-Salpeter equation with quark-exchange interaction when irreducible 3-q…
Octet and Decuplet Baryons in a Covariant and Confining Diquark-Quark Model
M. Oettel, G. Hellstern, R. Alkofer +1
The baryon octet and decuplet masses and Bethe-Salpeter vertex and wave functions are calculated in the ladder approximation to the quark exchange between a scalar or axialvector d…
