We report on double-differential inclusive cross-sections of the production of secondary protons, deuterons, and charged pions and kaons, in the interactions with a 5% nuclear interaction length thick stationary beryllium target, of a +8.9 GeV/c proton and pion beam, and a -8.0 GeV/c pion beam. Results are given for secondary particles with production angles between 20 and 125 degrees.

Study of the A-dependence of Inclusive $p$, $\bar{p}$, $\Lambda$ and $\bar{\Lambda}$ Production in $\pi^\pm$ Nucleus Interactions at 30-{GeV}/$c$

We present the first results on the production of fast (p>10 GeV/c)p,\(\bar p\), Λ and\(\bar \Lambda \) from π± hydrogen and nucleus interactions at 30 GeV/c using the CERN Ω′ spectrometer. We have used five nuclear targets (C, Al, Cu, Sn, Pb) to study theA-dependence of the inclusive particle distributions in the region 0.3<xF<0.6. The high statistical level of our experiment allows us to demonstrate the differentA-behaviour of baryon and antibaryon inclusive reactions. We relate this difference to the final state interaction inside a nucleus using the formation-zone model.

Study of Pion Absorption Mechanisms in He-4 and Other Nuclei

Phys.Rev.Lett. 39 (1977) 1601-1604, 1977.
Inspire Record 126555 DOI 10.17182/hepdata.20984

The spectrum and yield of protons produced by 60-, 100-, and 200-MeV π+ and π− beams on targets of He4, C12, Ni62, and Ta181 have been measured at 45° and 90°. A distinct high-energy component is seen in the protons from He4, which is consistent with a two-body absorption mechanism. Its cross section at 220 MeV is somewhat larger than calculated from the π+ + D process. Possible evidence is also seen for multinucleon absorption modes. The data on heavier nuclei are consistent with earlier experiments.

Experimental Study of the a-Dependence of Inclusive Hadron Fragmentation

Phys.Rev.D 27 (1983) 2580, 1983.
Inspire Record 12592 DOI 10.17182/hepdata.23823

Data are presented on the inclusive production of π±, K±, p, and p¯ for π+, K+, and protons incident on nuclear targets at 100 GeV. The results cover the kinematic range 30≤P≤88 GeV/c for Pt=0.3 and 0.5 GeV/c. The observed A dependence of the invariant cross sections exhibits remarkable simplicity, which does not naturally follow from current models of particle production. The results show that the hypothesis of limiting fragmentation can be extended to include collisions with nuclei.

PARTICLE MULTIPLICITIES AND MULTIPLICITY CORRELATIONS OBSERVED IN pi p COLLISIONS WITH HE NE NUCLEI IN A STREAMER CHAMBER

Allen, R.C. ; Kanofsky, A.S. ; Hasan, M.A. ;
Phys.Rev.C 27 (1983) 670-681, 1983.
Inspire Record 8194 DOI 10.17182/hepdata.38068

We have measured the multiplicities of particles emitted in collisions between π's and p's of 1.5 to 2.5 GeV/c momentum with He and Ne nuclei in a streamer chamber. The chamber gas served as the target as well as the detecting medium. Because of the low density and 4π solid angle of the detector, it was possible to detect nuclear fragments with energies less than 5 MeV, and to essentially count all the particles emitted in a collision. Event distributions as a function of track multiplicity were obtained as well as correlated event distributions. NUCLEAR REACTIONS He (proton or pion, fragments and pions), Ne (proton or pion, fragments and pions), E=1.5, 2.0, 2.5 BeV/c; streamer chamber gas used as target with fragment energies as low as 5 MeV. Measured multiplicities and correlations of produced particle types.
