On unifying the description of meson and baryon properties
G. Eichmann, I. C. Cloet, R. Alkofer +2
A Poincare' covariant Faddeev equation is presented, which enables the simultaneous prediction of meson and baryon observables using the leading-order in a truncation of the Dyson-…
Soft gluons are heavy and rowdy
Reinhard Alkofer, Pedro Bicudo, Stephen R. Cotanch +2
We study dynamical mass generation in pure Yang-Mills theory and report on a recently developed ansatz that exactly solves the tower of Dyson-Schwinger equations in Landau gauge at…
Partial-wave decomposition of the Faddeev amplitude of a Poincaré-invariant three-fermion bound state
Reinhard Alkofer, Martin Oettel
A partial-wave decomposition of the Faddeev amplitude of a Poincare-invariant three-fermion bound state is presented. Some implications for the properties of the nucleon as relativ…
Kugo-Ojima confinement and QCD Green's functions in covariant gauges
Reinhard Alkofer, Christian S. Fischer, Lorenz von Smekal
In Landau gauge QCD the Kugo-Ojima confinement criterion and its relation to the infrared behaviour of the gluon and ghost propagators are reviewed. It is demonstrated that the rea…
Pair Creation and an X-ray Free Electron Laser
R. Alkofer, M. B. Hecht, C. D. Roberts +2
Using a quantum kinetic equation coupled to Maxwell's equation we study the possibility that focused beams at proposed X-ray free electron laser facilities can generate electric fi…
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…
