Abstract: (Elsevier)

A ππ and KK̄ coupled channels scheme, with separable s wave interaction, allows to discuss, from a hadronic point of view, some properties of the f 0 (975) meson. An intriguing case where the weak binding and narrow width are crucially related to the coupling of the channels leads to some interesting consequences for the f 0 (975) production in nuclear matter.
