Study of the axial anomaly in the (gamma-proton going to charged-pion neutral-pion neutron) reaction at low t using the clas and the photon tagger
While the agreement between theory and experiment is excellent for the π 0 → 2γ reaction, other reactions that proceed through the axial anomaly have been poorly tested. For example the existing measurement of the γ → 3π amplitude, F3π, is in poor agreement with theory. In the limit of low s and t,...
