Mass dependence of pion-pion phase shifts within standard and unitarized ChPT versus Lattice results
J. Nebreda, J. R. Pelaez, G. Rios
We report on our recent results in the study of the chiral extrapolation of the phase-shifts in elastic pion-pion scattering, using both standard and unitarized ChPT to one and two…
Chiral extrapolation of pion-pion scattering phase shifts within standard and unitarized Chiral Perturbation Theory
J. Nebreda, J. R. Pelaez, G. Rios
We calculate the pion-pion elastic scattering phase shifts for pion masses from the chiral limit to values of interest for lattice studies. At low energies, we use the standard Chi…
Quark mass dependence of the rho and sigma from dispersion relations and Chiral Perturbation Theory
C. Hanhart, J. R. Pelaez, G. Rios
We use the one-loop Chiral Perturbation Theory pion-pion scattering amplitude and dispersion theory in the form of the inverse amplitude method, to study the quark mass dependence…
Meson resonances from unitarized meson scattering at one loop in Chiral Perturbation Theory
J. R. Pelaez, A. Gomez Nicola, .
We show the results for the scattering poles associated to the rho, f0, a0, K*, sigma and kappa resonances in meson-meson scattering. Our amplitudes are obtained from the complete…
Complete meson-meson scattering within one loop in Chiral Perturbation Theory: Unitarization and resonances
J. R. Pelaez, A. Gomez Nicola
We review our recent one-loop calculation of all the two meson scattering amplitudes within SU(3) Chiral Perturbation Theory, i.e. with pions, kaons and etas. By unitarizing these…
Unitarization of the complete meson-meson scattering at one loop in Chiral Perturbation Theory
J. R. Pelaez, A. Gomez Nicola
We report on our one-loop calculation of all the two meson scattering amplitudes within SU(3) Chiral Perturbation Theory, i.e. with pions, kaons and etas. Once the amplitudes are u…
