Investigation on exclusive beam asymmetry measurements of e + p → e + p + π0 process at CLAS12

MesonEx experiment at CLAS12 studies exotic mesons production. Investigating exclusive π0 production is crucial to understand the viability of the fundamental ηπ reaction. These studies are focused on the beam asymmetry Σ calculation and the comparison of the latter with the same obtained by GlueX and SLAC experiments. [Al Ghoul, H. et al. (2017). “Measurement of the beam asymmetry Σ for π0 and η photoproduction on the proton at Eγ = 9 GeV”. In: Physical Review C 95.4.] As the outcomes of these experiments shows significant discrepancies, the results provided by CLAS12 can be critical in the exotic meson production studies. In detail, the aim of the present work is a feasibility investigation of the π0 beam asymmetry measurement of quasi-real photoproduction at CLAS12 using the CLAS12 Forward Tagger detector.
