A coupled channel unitary chiral approach to the meson-meson interaction and pion-pion scattering in a nuclear medium
E. Oset, J. A. Oller, J. R. Peláez +2
A new tool which combines chiral perturbation theory and unitarity in coupled channels is applied with success to the study of the meson-meson interaction, extending the theoretica…
KbarN interaction and Kaons in the nuclear medium
A. Ramos, E. Oset
The s-wave meson-nucleon interaction in the S=-1 sector is studied by means of a coupled-channel Lippmann Schwinger equation, using the lowest order chiral Lagrangian and a cut off…
Two Pion Production in Nucleon-Nucleon Collisions at Intermediate Energies
L. Alvarez-Ruso, E. Oset, E. Hernandez
We have developed a model for the N N --> N N pi pi reaction and evaluated cross sections for the different charged channels. The low energy part of those channels where the pions…
Meson-Meson and Meson-Baryon Interactions in a chiral Non-perturbative Approach
E. Oset, J. A. Oller, J. R. Pelaez +1
A qualitative account of the meson-meson and meson-baryon interactions using chiral Lagrangians and the inverse amplitude method in coupled channels is done. The method, imposing e…
Nuclear effects in the F3 structure function
E. Marco, E. Oset, S. K. Singh
By using a relativistic framework and accurate nuclear spectral functions we evaluate the ratio F_{3A}/AF_{3N} of deep inelastic neutrino scattering. Parametrizations of this ratio…
