Abstract

We have studied the

ϕ (1020) f_{0} (980)

S

-wave scattering at energies around threshold employing chiral Lagrangians coupled to vector mesons through minimal coupling. The interaction kernel is obtained by considering the

f_{0} (980)

as a

K \bar{K}

bound state. The

Y (2175)

resonance is generated in this approach by the self-interactions between the

ϕ (1020)

and the

f_{0} (980)

resonances. We are able to describe the

e^{+} e^{-} \to ϕ (1020) f_{0} (980)

recent scattering data to test experimentally our scattering amplitudes, concluding that the

Y (2175)

resonance has a large

ϕ (1020) f_{0} (980)

meson-meson component.
