HARP Collaboration results on the proton-nuclei interactions at few GeV energies
arXiv:0806.3957
Abstract
Recent results obtained by the HARP collaboration on the measurements of the double-differential production cross-section of positive and negative pions in proton interactions with nuclear targets from Beryllium to Lead are presented. They cover production at small angles (30-210 mrad) and relatively large momenta up to 8 GeV/c as well as large angles (0.35 - 2.15 rad) and small momenta (0.1 - 0.8 GeV/c). These results are relevant for a detailed understanding of neutrino fluxes in accelerator neutrino experiments, better prediction of atmospheric neutrino fluxes, optimization of a future neutrino factory design and for improvement of hadronic generators widely used by the HEP community in the simulation of hadronic interactions.
