Cross-sections of large-angle hadron production in proton– and pion–nucleus interactions IV: copper nuclei and beam momenta from ±3 GeV/c to ±15 GeV/c

Abstract

We report on double-differential inclusive crosssections of the production of secondary protons, charged pions, and deuterons, in the interactions with a 5% λ abs thick stationary copper target, of proton and pion beams with momentum from ±3 GeV/c to ±15 GeV/c. Results are given for secondary particles with production angles 20°< θ < 125°. The inclusive pion production cross-sections are compared to those on beryllium and tantalum, published by us recently.PACS 13.85.Ni · 25.40.Qa

Cross-sections of large-angle hadron production in proton– and pion–nucleus interactions VIII: aluminium nuclei and beam momenta from ±3 GeV/c to ±15 GeV/c

“…The discrepancy between our results and those published by the HARP Collaboration is evident. It shows the same pattern as observed in inclusive cross-sections off other target nuclei [2][3][4][5][6][7][8]. We hold that the discrepancy is caused by problems in the HARP Collaboration's data analysis, discussed in detail in Refs.…”

“…The second paper [3] presented results for all beam momenta from this Be target. The third [4], fourth [5], fifth [6], sixth [7], and seventh [8] papers presented results from the interactions with 5% λ int tantalum, copper, lead, carbon, and tin targets. In this paper, we report on the large-angle production (polar angle θ in the range 20 • < θ < 125 • ) of secondary protons and charged pions, and of deuterons, in the interactions with a 5% λ int aluminium target of protons and pions with beam momenta of ±3.0, ±5.0, ±8.0, +12.9, −12.0, and ±15.0 GeV/c.…”

“…FRITIOF's predictions are shown for beam π + 's. 5 FRITIOF largely underestimates deuteron production. 8 Comparison of charged-pion production on beryllium, copper, tantalum, and lead Figure 9 presents a comparison between the inclusive crosssections of π + and π − production, integrated over the secondaries' momentum range 0.2 < p < 1.0 GeV/c and 2) nuclei.…”
