Differential cross sections as a function of transverse momentum are presented for the production at ∼90° (in the c.m. system) of π±, K±, p, and p¯ in p-nucleus collisions at incident proton energies of 200 and 300 GeV.

Production of Massive Muon Pairs by 300-GeV and 400-GeV Protons

Kluberg, L. ; Piroue, P.A. ; Sumner, Richard L. ; et al.

Phys.Rev.Lett. 37 (1976) 1451, 1976.

Inspire Record 4051 DOI 10.17182/hepdata.1201

We have observed muon pairs with effective masses in the range 7<~Mμμ<~11 GeV/c2 produced by 300- and 400-GeV protons incident on a Cu target at Fermilab. The production cross section per nucleon, dσdMμμ, for 400-GeV incident protons is found to fall from 1 × 10−36 cm2/(GeV/c2) at Mμμ=7.7 GeV/c2 to 2.7 × 10−38 cm2/(GeV/c2) at Mμμ=11.2 GeV/c2. We find that a significant fraction of the observed direct single muons come from high-mass dimuons.

Measurement of Cross-sections and Asymmetry Parameters for the Production of Charged Pions From Various Nuclei by 585-{MeV} Protons

Crawford, J.F. ; Daum, M. ; Eaton, G.H. ; et al.

Phys.Rev.C 22 (1980) 1184-1196, 1980.

Inspire Record 143030 DOI 10.17182/hepdata.26362

We have measured the differential cross section d2σdΩdTπ and the polarization parameter P for the production of π+ and π− in various target nuclei (H1, H2, Be, C, O, Al, Ni, Cu, Mo, and Pb) by protons with a kinetic energy of 585 MeV, for production angles θπ=22.5°, 45°, 60°, 90°, and 135°, and for pion kinetic energies Tπ of 24, 35, 46, 88, 151, 192, and 254 MeV (all quantities in the laboratory system). Our data disagree strongly with recent data for 580-MeV protons. On the other hand, for pion energies up to 150 MeV, our cross sections differ little from those measured for a proton energy of 730 MeV. For nuclei with A>20, the total production cross sections σ(π+) and σ(π−) show the Z13 and N23 proportionality expected from theoretical arguments. There is evidence in our data of a shift of the π+ energy distributions compared to the π− distributions due to the effects of the Coulomb field of the nuclear protons on the emitted pions. NUCLEAR REACTIONS H1, H2, Be, C, O, Al, Ni, Cu, Mo, Pb p, π±, Tp=585 MeV; measured σ(Tπ, θπ) and asymmetry parameter P(Tπ, θπ).

Measurements of the invariant cross sections for the reaction p(400 GeV)+(Li6, Be,C,Al,Cu,Ta)→(π±, K±)+X at laboratory angles from 70° to 160° are reported. Upper limits for p¯ production are given. Comparisons of the data are made using several scaling variables. NUCLEAR REACTIONS Inclusive cross section; 400 GeV incident protons; Li6, Be, C, Al, Cu, Ta targets; production of π, K, and p¯; lab angles 70° to 160°.

π+ meson production in low-energy proton collisions with carbon and copper nuclei

Akimov, Yu.K. ; Gajsak, I.I. ; Guber, F.F. ; et al.

JINR-1-80-294, 1980.

Inspire Record 1395696 DOI 10.17182/hepdata.39684

Differential and double differential cross sections of positive pion production by 240 MeV protons on carbon and copper nuclei are measured. The energy dependence of differential cross section for copper nucleus at 90 deg angle within the 240-500 MeV energy range of protons and angular dependence of the integrated differential cross section are obtained. It is shown that the differential cross section at 250 MeV is 80 times less than that at 585 MeV
