Inclusive π±, ϱ0 and Δ++ reactions photoproduced on neutrons and protons at 7.5 GeV

Abstract A comparison between the reactions γ p → π +- + anything and γ n → π +- + anything has been carried out with a linearly polarized photon beam of 7.5 GeV incident energy. The data has been analysed in terms of the structure functions F ( x ), F ( P ∥) and F ( P ⊥ 2 ). The reaction γ N → ϱ 0 + anything has been investigated and found to have similar behaviour as leading particles in hadron induced reactions as expected from the vector dominance model. Finally the reaction γ p → Δ ++ + anything was found to exhibit backward leading particle features and to be consistent with a one pion exchange mechanism.
