摘要：

We report here on recent advances that shed light on the topic of scalar meson sector, which is controversial up to date. We study the scattering and spectroscopy of the strongly interacting mesons in coupled channels with quantum numbers J(PC) = 0(++) and I = 0 and I = 1/2, up to a center of mass energy root s less than or similar to 2 GeV. Our framework is based on Unitary Chiral Perturbation Theory, but extended now to include many more channels. The resonant content of our fits is discussed, with the appearence of sigma, f(0)(980), f(0)(1310), f(0)(1500), f(0)(1710) and f(0)(1790) for I = 0 and the. and the K-0* (1430) for I = 1/2.
