Nonlocal calculation for nonstrange dibaryons and tribaryons
R. D. Mota, A. Valcarce, F. Fernández +2
We study the possible existence of nonstrange dibaryons and tribaryons by solving the bound-state problem of the two- and three-body systems composed of nucleons and deltas. The tw…
Chiral NN model and Ay puzzle
D. R. Entem, R. Machleidt, H. Witala
We analyze the results by chiral NN models for the two-nucleon system and calculate the predictions for the nucleon vector analyzing power of elastic nucleon-deuteron (Nd) scatteri…
Isobar Excitations and the Ground State of Nuclei
T. Frick, S. Kaiser, H. Müther +3
The influence of isobar components on the ground state properties of nuclear systems is investigated for nuclear matter as well as finite nuclei. Many-body wave functions, incl…
Comparison between chiral and meson-theoretic nucleon-nucleon potentials through (p,p') reactions
F. Sammarruca, D. Alonso, E. J. Stephenson
We use proton-nucleus reaction data at intermediate energies to test the emerging new generation of chiral nucleon-nucleon (NN) potentials. Predictions from a high quality one-boso…
Accurate Nucleon-Nucleon Potential Based upon Chiral Perturbation Theory
D. R. Entem, R. Machleidt
We present an accurate nucleon-nucleon () potential based upon chiral effective Lagrangians. The model includes one- and two-pion exchange contributions up to chiral order thre…
Towards a Model-Independent Low Momentum Nucleon-Nucleon Interaction
S. K. Bogner, T. T. S. Kuo, A. Schwenk +2
We provide evidence for a high precision model-independent low momentum nucleon-nucleon interaction. Performing a momentum-space renormalization group decimation, we find that the…
