International Conference on Hadron Physics (TROIA) (4. 2014. Canakkale, Turquia).
I thank the organizers of Troia14 for their kind hospitality and for creating such a nice scientific environment. Work supported by the Spanish Research contract FPA2011-27853-C02-02 and the EU-Research Infrastructure Integrating Activity “Study of Strongly Interacting Matter” (acronym HadronPhysics2, Grant Agreement n. 227431, 7th Framework Programme).
In this talk I briefly review the status of the f(0)(500) and f(0)(980) together with the other light scalar resonances, as well as the emerging picture of a non-ordinary light meson multiplet, paying particular attention to unitarized Chiral Perturbation Theory, large N-c, semi-local duality and Regge theory arguments.
