Phys.Lett.B 412 (1997) 407-413, 1997.
Inspire Record 459722 DOI 10.17182/hepdata.28265

Production of charged particles identified by a multi cell threshold Čerenkov counter in proton-tungsten and central sulphur-tungsten collisions at 200 GeV/ c per nucleon is discussed. The π ± , p and p production ratios and transverse mass spectra at central rapidity and p T > 0.6 GeV/ c are presented and compared with results from other experiments at the same beam energy.

LOW-ENERGY PION YIELD AT HIGH-ENERGY ACCELERATORS AS A FUNCTION OF THE PRIMARY PROTON BEAM MOMENTUM

Nuovo Cim.A 100 (1988) 305-308, 1988.
Inspire Record 270462 DOI 10.17182/hepdata.37844

High yields of low-momentum pions were obtained from high-energy primary proton beams. The results are discussed, also with respect to the possibility of setting up cloud muon beams from the very lowmomentum poins produced by 10 GeV/c protons.

Observation of Large Transverse Momentum Muons Directly Produced by 300-GeV Protons

Boymond, J.P. ; Mermod, R. ; Piroue, P.A. ; et al.
Phys.Rev.Lett. 33 (1974) 112, 1974.
Inspire Record 1236 DOI 10.17182/hepdata.43753

We have observed muons produced directly in Cu and W targets by 300-GeV incident protons. We find a yield of muons which is approximately a constant fraction (0.8·10−4) of the pion yield for both positive and negative charges and for transverse momenta between 1.5 and 5.4 GeV/c.

Particle ratios of high x(t) hadrons in p A interactions at s**(1/2) = 38.8-GeV.

Straub, P.B. ; Jaffe, D.E. ; Glass, H.D. ; et al.
Phys.Rev.D 45 (1992) 3030-3037, 1992.
Inspire Record 342598 DOI 10.17182/hepdata.22727

We report measurements of the ratios K+π+, pπ+, K−π−, p¯π−, π−π+, K−K+, and p¯p for hadrons with 0.19<xt<0.62 produced in p−Be and p−W collisions at s=38.8 GeV. The K+π+ ratio at high xt gives the fragmentation-function ratio DuK+Duπ+ at high z. The high-xt K−π− ratio gives an upper limit for DdK−Ddπ− at high z. The pt dependence of pπ+ suggests that scattered constituent diquarks are the primary source of protons with pt<6 GeV/c. We also present species correlations in high-mass h+h− pairs. Strong K+K− and pp¯ correlations were observed.

Production of hadrons with large transverse momentum at 200, 300, and 400 GeV

The E100 collaboration Cronin, J.W. ; Frisch, Henry J. ; Shochet, M.J. ; et al.
Phys.Rev.D 11 (1975) 3105-3123, 1975.
Inspire Record 1327 DOI 10.17182/hepdata.24884

We have measured, as a function of transverse momentum (p⊥), the invariant cross section Edσd3p for the production of π±, K±, p, p¯, d, and d¯ in proton collisions with a tungsten (W) target at incident proton energies of 200, 300, and 400 GeV. The measurements were made in the region of 90° in the c.m. system of the incident proton and a single nucleon at rest. Measurements were also made with 300-GeV protons incident on Be, Ti, and W targets of equal interaction length. These p-nucleus measurements, which show a strong dependence on atomic number at high p⊥, were used to extract effective proton-nucleon cross sections by extrapolation to atomic number unity. At large values of the scaling variable x⊥=2p⊥s, where s is the square of the c.m. energy, the pion data are found to be well represented by the expression (s)−ne−ax⊥, with n=11.0±0.4 and a=36.0±0.4. x⊥<0.35, where similar measurements have been made at the CERN ISR, our data are in good agreement with the ISR data.

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

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.
