A Non-Perturbative Chiral Approach for Meson-Meson Interactions
J. A. Oller, F. Guerrero, E. Oset +1
A non-perturbative method which combines constraints from chiral symmetry breaking and coupled channel unitarity is used to describe meson-meson interactions up to \sqrt{s}\lesssim…
Recent progress on the chiral unitary approach to meson meson and meson baryon interactions
E. Oset, J. A. Oller, J. R. Pelaez +11
We report on recent progress on the chiral unitary approach, analogous to the effective range expansion in Quantum Mechanics, which is shown to have a much larger convergence radiu…
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…
Study of the resummation of chiral logarithms in the exponentiated expression for the pion form factor
Francisco Guerrero
From the properties of analyticity and unitarity it has been recently obtained an exponentiated expression for the pion form factor. In this work I show the validity of this expres…
Effective Field Theory Description of the Pion Form Factor
F. Guerrero, A. Pich
Using our present knowledge on effective hadronic theories, short-distance QCD information, the expansion, analyticity and unitarity, we derive an expression for the pion f…
Kaon Polarizabilities in Chiral Perturbation Theory
Francisco Guerrero, Joaquim Prades
We study the kaon polarizabilities in the framework of Chiral Perturbation Theory to order . For the neutral kaon we find that them vanish and they have the first non-zero con…
