Abstract

We report on the results of the first measurement of exclusive f0(980) meson photoproduction on protons for Eγ=3.03.8GeV and t=0.41.0GeV2. 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 γppπ+π. Clear evidence of the f0(980) meson was found in the interference between P and S waves at Mπ+π1GeV. The S-wave differential cross section integrated in the mass range of the f0(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 f0(980) meson has been measured in a photoproduction experiment.
