In this paper we report KLOE results on scalar mesons f0, a0 using the last parametrization of the Kaon Loop model and a new global fit to the vector pseudoscalar photon transitions in order to obtain the gluonium content of the η′ meson and the pseudoscalar mixing angle ϕP. Both data from scalars and pseudoscalars are combined in the framework of the instanton based model to infer the nature of the f0 and a0 mesons.

Abstract
In this paper we report KLOE results on scalar mesons f0, a0 using the last parametrization of the Kaon Loop model and a new global fit to the vector pseudoscalar photon transitions in order to obtain the gluonium content of the η′ meson and the pseudoscalar mixing angle ϕP. Both data from scalars and pseudoscalars are combined in the framework of the instanton based model to infer the nature of the f0 and a0 mesons.File in questo prodotto:
