EMC EFFECT ON P-A HIGH ENERGY COLLISION

  • According to the perturbative QCD method,we have calculated the P distributive cross sections,the Y distributive cross sections of the large P jets and the final state meson productivities in 800GeV/c Proton-Nucleus (Be,C,Al,Cu and Pb) collisions.The A dependence of the cross section at a given P was discussed by the EMC effect. The dσ/dP differential cross sections vs .P for various PA collisions are consistent with the new data.

Abstract: According to the perturbative QCD method,we have calculated the P distributive cross sections,the Y distributive cross sections of the large P jets and the final state meson productivities in 800GeV/c Proton-Nucleus (Be,C,Al,Cu and Pb) collisions.The A dependence of the cross section at a given P was discussed by the EMC effect. The dσ/dP differential cross sections vs .P for various PA collisions are consistent with the new data.
