Improved Unitarized Heavy Baryon Chiral Perturbation Theory for pion-nucleon Scattering to fourth order
A. Gomez Nicola, J. Nieves, J. R. Pelaez +1
We extend our previous analysis of the unitarized pion-nucleon scattering amplitude including up to fourth order terms in Heavy Baryon Chiral Perturbation Theory. We pay special at…
Large N_c behavior of light resonances in meson-meson scattering
J. R. Pelaez
By scaling the parameters of meson-meson unitarized Chiral Perturbation Theory amplitudes according to the QCD large N_c rules, one can study the spectroscopic nature of light meso…
Recent progress on the light meson resonance description from unitarized Chiral Perturbation Theory and large Nc
J. R. Pelaez
We present a brief account of the developments in the description of light meson resonances using unitarized extensions of the Chiral Perturbation Theory series, both in energy and…
Poles of light resonances from unitarized Chiral perturbation Theory and their large Nc behavior
J. R. Pelaez
We have recently completed the one loop calculation of meson-meson scattering within Chiral Perturbation Theory. Once unitarized, these amplitudes provide simultaneously a remarkab…
Light meson resonances from unitarized Chiral Perturbation Theory
J. R. Pelaez, A. Gomez Nicola
We report on our recent progress in the generation of resonant behavior in unitarized meson-meson scattering amplitudes obtained from Chiral Perturbation Theory. These amplitudes p…
