Alpha-Alpha scattering, chiral symmetry and 8Be lifetime
E. Ruiz Arriola
Alpha-alpha scattering is discussed in terms of a chiral two pion exchange potential which turns out to be attractive and singular at the origin, hence demanding renormalization. W…
Does it make any sense to talk about a Delta-isobar?
F. Kleefeld
It is shortly investigated, on what basis an experimentally observed resonance like the Delta(1232)-isobar can be embedded into the framework of Quantum Theory (QT), i.e. Quantum F…
ISI and FSI in NN-->NNX reactions
F. Kleefeld
The present status of the theoretical description of Initial (ISI) and Final State Interactions (FSI) in nucleon induced exclusive meson production processes close to threshold is…
Model-independent definition and determination of electromagnetic formfactors and multipole moments
F. Kleefeld
A theoretical method for the systematic definition and determination of Cartesian and spherical electromagnetic (onshell) formfactors and multipole moments for particles or composi…
ISI/FSI in Threshold Meson Production - Onshell Approach and Coulomb Problem
F. Kleefeld
The onshell description of Initial- and Final-State-Interactions (ISI and FSI) of threshold meson production reactions is reviewed. Existing onshell models and their offshell exten…
Consistent effective description of nucleonic resonances in an unitary relativistic field-theoretic way
F. Kleefeld
High energy strong interaction physics is successfully described by the local renormalizable gauge theory called Quantum-Chromo-Dynamics (QCD) with quarks and gluons as ``elementar…
