The equivalence theorem and the production of gravitinos after inflation
A. L. Maroto, J. R. Pelaez
We study the high-energy equivalence between helicity 1/2 gravitinos and goldstinos in order to calculate the production of gravitinos in time-dependent scalar and gravitational ba…
Photoproduction of meson and baryon resonances in a chiral unitary approach
E. Oset, E. Marco, J. C. Nacher +4
By means of a coupled channel non-perturbative unitary approach, it is possible to extend the strong constrains of Chiral Perturbation Theory to higher energies. In particular, it…
The Inverse Amplitude Method and Heavy Baryon Chiral Perturbation Theory applied to pion-nucleon scattering
J. R. Pelaez, A. Gomez Nicola
We report on our present work, where by means of the Inverse Amplitude Method we unitarize the elastic pion nucleon scattering amplitudes of Heavy Barion Chiral Perturbation Theory…
Resonances, Chiral Symmetry, Coupled Channel Unitarity and Effective Lagrangians
J. R. Pelaez, J. A. Oller, E. Oset
By means of a coupled channel non-perturbative unitary approach, it is possible to extend the strong constrains of Chiral Perturbation Theory to higher energies. In particular, it…
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…
