Precise determination of the sigma pole location from a dispersive analysis
R. Garcia-Martin, R. Kaminski, J. R. Pelaez
We review how the use of recent precise data on kaon decays together with forward dispersion relations (FDR) and Roy's equations allow us to determine the sigma resonance pole posi…
Precise analysis of pion-pion scattering data from Roy equations and forward dispersion relations
J. R. Pelaez, R. Garcia-Martin, R. Kaminski +1
We review our recent analysis of pion-pion scattering data in terms of Roy equations and Forward Dispersion Relations, and present some preliminary results in terms of a new set of…
decay within a chiral unitary approach revisited
E. Oset, J. R. Pelaez, L. Roca
In view of the recent experimental developments on the experimental side in the decay, and the fact that the Particle Data Group in the on line edition of 2007 report…
Chiral Extrapolation of light resonances from Unitarized Chiral Perturbation Theory
J. R. Pelaez, C. Hanhart, G. Rios
Both scalar and vector light resonances can be generated from the unitarization of one-loop chiral perturbation theory. This amounts to using in a dispersion relation the chiral ex…
Scalar mesons from Unitarized Chiral Perturbation Theory: N_c and quark mass dependences
J. R. Peláez, G. Ríos
We review recent studies of light scalar meson properties by means of unitarization techniques, obtained from dispersion theory, and applied to the Chiral Perturbation Theory expan…
The pion-pion scattering amplitude. III: Improving the analysis with forward dispersion relations and Roy equations
R. Kaminski, J. R. Pelaez, F. J. Yndurain
We complete and improve the fits to experimental scattering amplitudes, both at low and high energies, that we performed in the previous papers of this series. We then verify…
