초록

For the first time, differential cross sections and photon beam asymmetries were measured for the reaction gamma p -> f0(980) p -> pi 0 pi 0p by using a linearly polarized photon beam up to 2.4 GeV and a liquid hydrogen target. The f0(980) photoproduction signal was clearly observed owing to the absence of contributions from vector-meson photoproduction. The results indicate the t-channel exchange of vector mesons as a mechanism of the f0(980) photoproduction at E gamma approximate to 2.1 GeV, putting constraints on the nature of f0(980).
