Light scalars as tetraquarks or two-meson states from large Nc and unitarized Chiral Perturbation Theory

J. R. Pelaez

By means of unitarized Chiral Perturbation Theory it is possible to obtain a remarkable description of meson-meson scattering amplitudes up to 1.2 GeV, and generate poles associate…

The pion-pion scattering amplitude

J. R. Pelaez, F. J. Yndurain

We obtain reliable scattering amplitudes consistent with experimental data, both at low and high energies, and fulfilling appropriate analyticity properties. We do this by fir…
