Chiral symmetry and parametrization of scalar resonances
L. O. Arantes, M. R. Robilotta
The linear $\s$-model is used to study the effects of chiral symmetry in unitarized amplitudes incorporating scalar resonances. When just a single resonance is present, we show tha…

Relativistic two-pion exchange nucleon-nucleon potential: parametrized version
R. Higa, M. R. Robilotta, C. A. da Rocha
The chiral two-pion exchange nucleon-nucleon interaction has nowadays a rather firm conceptual basis, but depends on low-energy constants, which may be extracted from fits to data.…
