Scalar photoproduction on the proton at CLAS and GlueX energies

arXiv:1404.4511

Abstract

In this work we present the results of a theoretical analysis of the data on photoproduction of $f_{0} (980)$ meson in the laboratory photon energy between $3.0$ GeV and $3.8$ GeV. A comparison is done to the measurements performed by the CLAS collaboration at JLab accelerator for the exclusive reaction $γ p \to p f_{0} (980)$ . The differential and integrated total cross sections are also computed for the cases of the mesons $f_{0} (1500)$ , and $f_{0} (1710)$ , focusing on the GlueX energy regime with photon energy $E_{γ} = 9$ GeV.
