The Role of 5-quark Components on the Nucleon Form Factors
Q. B. Li, D. O. Riska
The covariant quark model is shown to allow a phenomenological description of the neutron electric form factor, G_E^n(Q^2), in the impulse approximation, provided that the wave fun…
The strangeness form factors of the proton
D. O. Riska, B. S. Zou
The present empirical information on the strangeness form factors indicates that the corresponding component in the proton is such that the subsystem has the fl…
Canonical Quantization of SU(3) Skyrme Model in a General Representation
D. Jurciukonis, E. Norvaisas, D. O. Riska
A complete canonical quantization of the SU(3) Skyrme model performed in the collective coordinate formalism in general irreducible representations. In the case of SU(3) the model…
D-state configurations in the electromagnetic form factors of the nucleon and the Delta(1232) resonance
B. Julia-Diaz, D. O. Riska
The electromagnetic transition form factors are calculated in the Poincaré covariant quark model in three forms of relativistic kinematics. Addition of state components t…
Bound States of Heavy Flavor Hyperons
F. Froemel, B. Julia-Diaz, D. O. Riska
Several realistic phenomenological nucleon-nucleon interaction models are employed to investigate the possibility of bound deuteron-like states of such heavy flavor hyperons and nu…
Axial Transition Form Factors and Pion Decay of Baryon Resonances
B. Julia-Diaz, D. O. Riska, F. Coester
The pion decay constants of the lowest orbitally excited states of the nucleon and the along with the corresponding axial transition form factors are calculated with Poin…
