Elastic Form Factors in Point-form Approach
M. Radici
Using the point-form approach to relativistic quantum mechanics, a covariant framework is presented for the calculation of proton and neutron electromagnetic form factors. Results…
Hadronic Decays of N and ΔResonances in a Chiral Quark Model
L. Theussl, R. F. Wagenbrunn, B. Desplanques +1
πand ηdecay modes of light baryon resonances are investigated within a chiral quark model whose hyperfine interaction is based on Goldstone-boson exchange. For the decay mechanism…
Covariant nucleon electromagnetic form factors from the Goldstone-boson-exchange quark model
R. F. Wagenbrunn, S. Boffi, W. Klink +2
We present a study of proton and neutron electromagnetic form factors for the recently proposed Goldstone-boson-exchange constituent quark model. Results for charge radii, magnetic…
Limits on the low energy antinucleon-nucleus annihilations from the Heisenberg principle
A. Bianconi, G. Bonomi, M. P. Bussa +3
We show that the quantum uncertainty principle puts some limits on the effectiveness of the antinucleon-nucleus annihilation at very low energies. This is caused by the fact that t…
A phenomenological analysis of antiproton interactions at low energies
A. Bianconi, G. Bonomi, M. P. Bussa +3
We present an optical potential analysis of the antiproton-proton interactions at low energies. Our optical potential is purely phenomenological, and has been parametrized on data…
Proton recoil polarization in exclusive (e,e'pp) reactions
C. Giusti, F. D. Pacati
The general formalism of nucleon recoil polarization in the () reaction is given. Numerical predictions are presented for the components of the outgoing proto…
