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

et al. 2012

We report on double-differential inclusive crosssections of the production of secondary protons, charged pions, and deuterons, in the interactions with a 5% λ int thick stationary aluminium 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 • . Cross-sections on aluminium nuclei are compared with cross-sections on beryllium, carbon, copper, tin, tantalum and lead nuclei.

We report on double-differential inclusive crosssections of the production of secondary protons, charged pions, and deuterons, in the interactions with a 5% λ int thick stationary lead 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°. Cross-sections on lead nuclei are compared with cross-sections on beryllium, copper, and tantalum nuclei.

“…They result primarily, but not exclusively, from a lack of understanding TPC track distortions and RPC timing signals. These problems, together with others that affect the HARP Collaboration's data analysis, are discussed in great detail in [15][16][17] and summarized in the Appendix of [1].…”

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

Comments on TPC and RPC calibrations reported by the HARP collaboration

Abstract: The HARP Collaboration recently published calibrations of their TPC and RPC detectors, and differential cross-sections of large-angle pion production in proton-nucleus collisions. We argue that these calibrations are biased and cross-sections based on them should not be trusted.
