00925njm 22002777a 4500 dc Peláez Sagredo, José Ramón author Gómez Nicola, Ángel author 2001 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 unitarized with the coupled channel Inverse Amplitude Method, they satisfy simultaneously the correct low-energy chiral constraints and unitarity. We obtain a remarkable description of meson-meson scattering data up to 1.2 GeV including the scattering lengths and seven light resonances. 0-7354-0046-6 10.1063/1.1435909 https://hdl.handle.net/20.500.14352/60963 http://dx.doi.org/10.1063/1.1435909 http://scitation.aip.org http://arxiv.org/abs/hep-ph/0109074 Unitarization of the complete meson-meson scattering at one loop in Chiral Perturbation Theory
