Phys.Rev.Lett. 43 (1979) 319, 1979.
Inspire Record 141771 DOI 10.17182/hepdata.9274

We present high-statistics results on the reactions a+p→c+X where a and c can be any of π±, K±, p, or p¯. The data were taken at 100 and 175 GeV/c incident momenta using the Fermilab Single-Arm Spectrometer operated over the kinematic range 0.2

Total Cross-Section for Hadronic Production by e+ e- Annihilation in the Total Center-Of-Mass Energy Range 1.42-GeV - 3.09-GeV

Bacci, C. ; Baldini Celio, R. ; Battistoni, G. ; et al.
Phys.Lett.B 86 (1979) 234-238, 1979.
Inspire Record 141722 DOI 10.17182/hepdata.27311

We report experimental results on the cross section for the reaction e + e − → hadrons as a function of the total c.m. energy in the range W = 1.42–3.09 GeV. The results, combined with those already existing below the charm threshold, clearly indicate a structure for R ( W ) = α ( e + e − → hadrons)/ α ( e + e − → μ + μ − ) in that energy region.

Study of the Reaction $e^+ e^- \to p \bar{p}$ in the Total Energy Range 1925-{MeV} - 2180-{MeV}

Delcourt, B. ; Derado, I. ; Bertrand, J.L. ; et al.
Phys.Lett.B 86 (1979) 395-398, 1979.
Inspire Record 141565 DOI 10.17182/hepdata.27308

The e + e − → p p cross section has been measured between 1925 and 2180 MeV. About 50 p p events were detected. The total cross section decreases from 1.31 ± 0.4 nb near 1937 MeV to 0.55 ± 0.2 nb near 2135 MeV. The proton form factors | G E | 2 and | G M | 2 , assumed identical, decrease from 0.15 ± 0.05 to 0.043 ± 0.015. They are an order of magnitude higher than predicted by the well-known dipole fit. The energy range has been scanned in steps of about 2 MeV. No significant structure was found in this p p sample.

The Contribution of $q \bar{q}$ Annihilations to Dimuon Production in $\pi N$ Interactions

Reece, C. ; LeBritton, J. ; McCal, D. ; et al.
Phys.Lett.B 85 (1979) 427-431, 1979.
Inspire Record 7886 DOI 10.17182/hepdata.27323

We present data on dimuon production by 16 GeV π + and π − beams on a Cu target. From the data we evaluate, for π − N collisions, the fraction of dimuon events that originate from the annihilation process q q ̄ → μ + μ − . Using this information the experimentally determined cross section for the process q q ̄ → μ + μ − is observed to be in agreement with the Drell-Yan model over a wide range of incident energies. The observed deviations from exact scaling are of the order predicted by QCD calculations for the Q 2 -dependence of the nucleon and the pion structure function.

Inclusive Production of $D$ and $K$ Mesons in $e^+ e^-$ Annihilation

Piccolo, M. ; Peruzzi, I. ; Rapidis, P.A. ; et al.
Phys.Lett.B 86 (1979) 220-224, 1979.
Inspire Record 141018 DOI 10.17182/hepdata.27301

We present measurements of the cross section for inclusive D and K meson production in e + e − annihilation in the center of mass energy range 3.6 to 5.8 GeV. D production accounts for most of the increase in the total cross section for hadron production in e + e − annihilation at energies above 4 GeV.

Channel Cross-sections and Two-body Reactions in $K^- p$ Interactions at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Givernaud, A. ; Denegri, D. ; Lewin, C. ; et al.
Nucl.Phys.B 160 (1979) 445-466, 1979.
Inspire Record 141995 DOI 10.17182/hepdata.34613

We present a systematic investigation of channel cross sections in K − p interactions at 32 GeV/ c . The energy dependence of these cross sections is discussed. We also investigate a few non-diffractive two-body reactions. The total cross sections of the two reactions K − p → K ∗− (890) p and K − p → K ∗− (1420) p have a markedly different energy behaviour. There is clear evidence for the reaction K − p → K ∗0 (890) N 0 (1688) ; its differnttial cross section exhibits a sharp forward slope of 24 ± 3 GeV −2 .

Experimental Tests of Quantum Chromodynamics in High $p_T$ Jet Production in 200-{GeV}/$c$ Hadron - Proton Collisions

Bromberg, C. ; Fox, G. ; Gomez, R. ; et al.
Phys.Rev.Lett. 43 (1979) 565, 1979.
Inspire Record 141467 DOI 10.17182/hepdata.52007

Data on inclusive jet production in the transverse-momentum (p⊥) range 0-8 GeV/c for 200-GeV/c p, π−, π+, K−, K+, and p¯ incident on a hydrogen target are presented. The jet cross section is fully corrected for losses and biases, and compared with the predictions of a model based on quantum chromodynamics. Both the absolute cross section and the inclusive charged-particle distributions inside and outside the jet are in qualitative agreement with the model.
