Abstract

Total cross section for the double neutral pion photoproduction off the proton is presented in the incident photon energy range of 0.58 to 1.15 GeV. The data were accumulated in the years 2009-2010, recorded by a 4π EM calorimeter at ELPH, named FOREST. The number of recorded events obtained during this period is 1.6×10⁹ for a hydrogen target. Two neutral pions are reconstructed via detecting their decay products, four gammas (2π⁰ → 4γ). Compared to the previous results obtained by other groups, our data are in good agreement with theirs within error bars.
