Old nuclear symmetries and large N(c) as long distance symmetries in the two nucleon system
E. Ruiz Arriola, A Calle Cordon
Wigner and Serber symmetries for the two-nucleon system provide unique examples of long distance symmetries in Nuclear Physics, i.e. symmetries of the meson exchange forces broken…
Serber symmetry, Large Nc and Yukawa-like One Boson Exchange Potentials
A. Calle Cordon, E. Ruiz Arriola
The Serber force has relative orbital parity symmetry and requires vanishing NN interactions in partial waves with odd angular momentum. We illustrate how this property is well ful…
A Two Potential Formula and its Application to Proton-Proton Scattering
M. Pavon Valderrama, E. Ruiz Arriola
Within the framework of potential scattering theory we derive an analytical two-potential formula for the on-shell partial wave scattering amplitude. This formula embodies a large…
Wigner symmetry, Large Nc and Renormalized One Boson Exchange Potential
A. Calle Cordon, E. Ruiz Arriola
Wigner symmetry in Nuclear Physics provides a unique example of a non-perturbative long distance symmetry, a symmetry strongly broken at short distances. We analyse the consequence…
Chiral Expansion, Renormalization and the Nuclear Force
E. Ruiz Arriola, M. Pavon Valderrama
The renormalization of singular chiral potentials as applied to NN scattering and the structure of the deuteron is discussed. It is shown how zero range theories may be implemented…
