Poincare-invariant spectator-model currents for electroweak nucleon form factors
R. F. Wagenbrunn, T. Melde, W. Plessas
The relativistic constituent quark model of low-energy quantum chromodynamics is found to yield a consistent picture of the electroweak structure of the nucleons. Notably, the elec…
Quantum chaos in QCD and hadrons
Harald Markum, Willibald Plessas, Rainer Pullirsch +2
This article is the written version of a talk delivered at the Workshop on Nonlinear Dynamics and Fundamental Interactions in Tashkent and starts with an introduction into quantum…
Spectator-model operators in point-form relativistic quantum mechanics
T. Melde, L. Canton, W. Plessas +1
We address the construction of transition operators for electromagnetic, weak, and hadronic reactions of relativistic few-quark systems along the spectator model. While the problem…
Strong Decays of Baryons
T. Melde, L. Canton, W. Plessas +1
A Poincare-invariant description of mesonic baryon resonance decays is presented following the point form of relativistic quantum mechanics. In this contribution we focus on pionic…
Nucleon electromagnetic and axial form factors in point-form relativistic quantum mechanics
R. F. Wagenbrunn, S. Boffi, L. Ya. Glozman +3
Results for the proton and neutron electric and magnetic form factors as well as the nucleon axial form factor are presented for constituent quark models, based on either one-gluon…
Relativistic Study of Mesonic Baryon Resonance Decays
T. Melde, R. F. Wagenbrunn, W. Plessas
Mesonic baryon resonance decays are calculated from constituent quark models along a Poincaré-invariant generalization of the elementary emission model. Covariant results of pionic…
