Inclusive Double Charge Exchange $\pi^-$ Production at 100 GeV/c

Cutts, D. ; Dulude, R. ; Lanou, R.E. ; et al.

Phys.Rev.Lett. 40 (1978) 141, 1978.

Inspire Record 121767 DOI 10.17182/hepdata.20919

Measurements of inclusive cross sections at 100 GeV/c are presented for the double-charge-exchange reactions a+p→π−X with a=π, K, or p. The measurements covered a kinematic range in the Feynman x variable of 0.3<~x<~0.9 at transverse momenta of 0.3 and 0.5 GeV/c. A model summing the contributions from resonance production and from inclusive central-region π− production is used to fit the data and demonstrates the importance of resonance production via one-pion exchange for large values of the Feynman x.

Measurement of the Dijet Cross-Section in 400-GeV p p Collisions

The E-609 collaboration Arenton, M.W. ; Ditzler, W.R. ; Fields, T.H. ; et al.

Phys.Rev.Lett. 53 (1984) 1988, 1984.

Inspire Record 15116 DOI 10.17182/hepdata.23566

The invariant cross section for production of jet pairs in 400-GeV/c pp interactions has been measured as a function of pT in the pT range 4 to 9 GeV/c. The results are in good agreement with predictions of perturbative QCD models.

Inclusive Production of Direct Photons in 200-{GeV}/$c$ Collisions

McLaughlin, M. ; Biel, J. ; Bromberg, C. ; et al.

Phys.Rev.Lett. 51 (1983) 971, 1983.

Inspire Record 191763 DOI 10.17182/hepdata.20473

The authors have measured the inclusive production of direct photons in the transverse momentum (pT) range 2.1-5.0 GeV/c in 200-GeV/c collisions of protons and π+ mesons on a carbon target. A significant yield of direct photons was observed for pT>2.5 GeV/c. The invariant cross section for direct-photon production, when compared with measurements from the CERN intersecting storage rings, can be expressed in terms of pT and xT=2pTs as (42±14)(1−xT)8.1±1.0pT−6.6±0.3 μb/GeV2 for the c.m. energy range from s=19.4 to 63 GeV, and for the xT range from 0.2 to 0.5.

Nuclear Enhancement of pi0 and eta mesons Produced at Large Transverse Momenta

Povlis, J. ; Biel, J. ; Bromberg, C. ; et al.

Phys.Rev.Lett. 51 (1983) 967, 1983.

Inspire Record 191764 DOI 10.17182/hepdata.20477

The authors have measured the large-pT inclusive cross sections for π0 and η production near 90° in the center-of-mass system in 200-GeV/c π+ and proton collisions with beryllium, carbon, and aluminum targets. The cross section for both π0 and η mesons rises with increasing nucleon number (A) of the target nucleus as Aα, with α>1. The ratio of the π0 yield in pA collisions to that in π+A collisions decreases with increasing pT.

Experimental Study of the a-Dependence of Inclusive Hadron Fragmentation

Barton, D.S. ; Brandenburg, G.W. ; Busza, W. ; et al.

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.

PHOTOPRODUCTION OF eta MESONS AT 9.7-GeV

Nelson, C.A., Jr. ; Abramson, J. ; Andrews, D.E. ; et al.

Phys.Rev.D 19 (1979) 1931, 1979.

Inspire Record 132567 DOI 10.17182/hepdata.24307

Inclusive η photoproduction has been studied at 9.7 GeV, on hydrogen and deuterium targets. A simple, parameter-free ρ0-dominance model adequately fits the forward cross sections, but overestimates the cross section at large momentum transfer.

Experimental Study of Low $P_t$ Hadron Fragmentation

Cutts, D. ; Dulude, R.S. ; Lanou, R.E., Jr. ; et al.

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<x<1.0 and pt<~1.0 GeV/c. Investigating the x dependence of the data, we find agreement with a quark-parton picture, namely the cross sections have a power-law behavior in 1−x independent of pbeam and pt.
