ϕ(1020)f0(980)S-wave scattering and the Y(2175) resonance
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 KK 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 - → 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.
