On the \phi(1020)f_0(980) S-wave scattering and the Y(2175) resonance

Understand

We have studied the \phi(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 \phi(1020) and the f_0(980) resonances.
• We are able to describe the e^+e^-\to \phi(1020)f_0(980) recent scattering data to test experimentally our scattering amplitudes, concluding that the Y(2175) resonance has a large \phi(1020)f_0(980) meson-meson component.
