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…
N/D Description of Two Meson Amplitudes and Chiral Symmetry
J. A. Oller, E. Oset
The most general structure of an elastic partial wave amplitude when the unphysical cuts are neglected is deduced in terms of the N/D method. This result is then matched to lowest…
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…
KK bar scattering amplitude to one loop in chiral perturbation theory, its unitarization and pion form factors
Francisco Guerrero, Jose Antonio Oller
We have calculated the KK bar --> KK bar scattering amplitude to next to leading order in Chiral Perturbation Theory. Then, making use of a unitarization procedure with one or seve…
Meson-Meson interaction in a non-perturbative chiral approach
J. A. Oller, E. Oset, J. R. Pelaez
A non-perturbative method which combines constraints from chiral symmetry breaking and coupled channel unitarity is used to describe the meson-meson interaction up to about 1.2 GeV…
Non-perturbative chiral approach to Kp -->gamma Y reactions
T. -S. H. Lee, J. A. Oller, E. Oset +1
A recently developed nonperturbative chiral approach to describe the S=-1 meson-baryon reactions has been extended to investigate the near threshold reactions.…
