Abstract:
The backward production of protons in the reaction π-A → p↓X is studied at 40 GeV incident energy with the different nuclear targets : C, Cu, Pb. The structure function shows a slope independent of the target atomic weight A and slightly dependent on the proton production angle. The invariant cross-section, normalized to the nucleon, increases with A up to a plateau which varies with the incident energy. Finally the ratios R = (F A/A)/(FC/AC) and n = ln(F A/FC)/ln(A/AC), where F = (E/p 2)(d2σ/(d p dΩ)), show a flat dependence on the momentum of the proton backward produced. These results are in favour of few-nucleon correlation models.
