dc.description.abstract | We study the e(+)e(-) -> Φππ reaction for pions in an isoscalar s wave which is dominated by loop mechanisms. For kaon loops we start from the conventional R chi PT, but use the unitarized amplitude for K[overline K]-ππ scattering and the full kaon form factor instead of the lowest order terms. We study also effects of vector mesons using R chi PT supplemented with the conventional anomalous term for VVP interactions and taking into account the effects of heavy vector mesons in the K*K transition form factor. We find a peak in m(π π) around the f(0)(980) as in the experiment. Selecting the Φf(0)(980) contribution as a function of the e(+)e(-) energy we also reproduce the experimental data except for a narrow peak, yielding support to the existence of a 1(--) resonance above the Φf(0)(980) threshold, coupling strongly to this state. | en_US |
