Abstract

The study of processes with production of proton pairs with small excitation energy (diprotons) provides a new approach to hadron interactions at intermediate energies. It is especially instructive due to comparison with processes where a deuteron is produced in the same kinematics. Provided that the momentum transfer is high enough the diprotons are found presumably in the ¹S₀ state, and this simplifies the theoretical analysis. The ANKE spectrometer provides the possibility to select the diprotons with sufficiently high excitation energy resolution. A number of processes including pp → {pp}_sn, production of one and two pions in pN collisions, and the pp → {pp}_sγ process, have been investigated.
