First Measurement of Differential Cross Sections and Photon Beam Asymmetries for Photoproduction of the f&sub(0)(980) Meson Decaying into *p*0*p*0 at E&sub(*g) < 2.4 GeV / N.Muramatsu, E.A.Strokovsky, [a.o.] // Physical Review C [Electronic resource]. – 2023. – Vol.107, No.4. – P.L042201. – URL: https://doi.org/10.1103/PhysRevC.107.L042201. – Bibliogr.:27.

For the first time, differential cross sections and photon beam asymmetries were measured for the reaction γp→f0(980)p→π0π0p by using a linearly polarized photon beam up to 2.4GeV 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 Eγ≈2.1GeV, putting constraints on the nature of f0(980).
