"Measurement of Direct ƒ0(980) Photoproduction on the" by M. Battaglieri, Gerard P. Gilfoyle et al.
We report on the results of the first measurement of exclusive ƒ0(980) meson photoproduction on protons for Eγ = 3.0–3.8 GeV and -t = 0.4–1.0 GeV2. Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator Facility. The resonance was detected via its decay in the π+ π- channel by performing a partial wave analysis of the reaction γ p → pπ+π-. Clear evidence of the ƒ0(980) meson was found in the interference between P and S waves at Mπ+π- ∼ 1 GeV. The S-wave differential cross section integrated in the mass range of the ƒ0(980) was found to be a factor of about 50 smaller than the cross section for the ρ meson. This is the first time the ƒ0(980) meson has been measured in a photoproduction experiment.
