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…

Enhanced non-quark-antiquark and non-glueball Nc behavior of light scalar mesons

J. Nebreda, J. R. Pelaez, G. Rios

We show that the latest and very precise dispersive data analyses require a large and very unnat- ural fine-tuning of the 1/Nc expansion at Nc = 3 if the f_0(600) and K(800) light…

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…
