The pion-cloud contribution to the electromagnetic nucleon structure
D. Kupelwieser, W. Schweiger
The present contribution continues and extends foregoing work on the calculation of electroweak form factors of hadrons using the point-form of relativistic quantum mechanics. Here…
The Pion-Cloud Contribution to the Electromagnetic Nucleon Form Factors
Daniel Kupelwieser, Wolfgang Schweiger
We study the electromagnetic structure of the nucleon within a hybrid constituent-quark model that comprises, in addition to the valence component, also a + non-valence…
Meson-cloud effects in the electromagnetic nucleon structure
Daniel Kupelwieser, Wolfgang Schweiger
We study how the electromagnetic structure of the nucleon is influenced by a pion cloud. To this aim we make use of a constituent-quark model with instantaneous confinement and a p…
The Schwinger Model in Point Form
Daniel Kupelwieser, Wolfgang Schweiger, William H. Klink
We attempt to solve the Schwinger model, i.e. massless QED in 1+1 dimensions, by quantizing it on a space-time hyperboloid x_μx^μ=τ^2. The Fock-space representation of the 2-moment…
