Measurement of the total proton proton cross-section at the ISR

Amendolia, S.R. ; Bellettini, G. ; Braccini, P.L. ; et al.
Phys.Lett.B 44 (1973) 119-124, 1973.
Inspire Record 83730 DOI 10.17182/hepdata.28114

We present the first results of a measurement of the total cross-section σ T in proton-proton collisions at equivalent laboratory momenta between 291 and 1480 GeV/ c at the CERN Intersecting Storage Rings (ISR). The method is based on the measurement of the ratio of the total interaction rate and the machine luminosity. The data show an increase of about 10% in σ T in this energy interval.

We present the first results of an experiment at the CERN intersecting storage rings, which measures the total cross-section in proton-proton collisions. The equivalent laboratory momenta are 291, 496, 1068 and 1480 GeV/c. We have made a direct measurement of αT as the ratio between the total interaction rate and the machine luminosity. The present paper gives a detailed description of the experimental apparatus and of the analysis procedure. We find that αT increases by about 10% in the energy region studied.

Inclusive eta Production at Large Transverse Momenta

Donaldson, G.J. ; Gordon, H.A. ; Lai, K.-W. ; et al.
Phys.Rev.Lett. 40 (1978) 684, 1978.
Inspire Record 122477 DOI 10.17182/hepdata.20917

We have measured the ratio of inclusive production of η to π0 at transverse momenta above 1.5 GeV/c. Results are presented for various meson and proton beams with momenta of 100, 200, and 300 GeV/c incident upon a hydrogen target. The ηπ0 production ratio is found to be independent of incident beam momentum and of the transverse and longitudinal momenta of production. The ratio for pion- and proton-induced reactions is 0.44 ± 0.05; for kaons, it is 0.74 ± 0.12.

Electroproduction of $\pi^0$ Mesons in the Resonance Region at $q^2=1.0$-{GeV}/$c^2$

Nucl.Phys.B 189 (1981) 1-14, 1981.
Inspire Record 155783 DOI 10.17182/hepdata.43833

Data are presented for the reaction ep → ep π 0 at a nominal momentum transfer squared of 1.0 (GeV/ c ) 2 . The data were obtained using an extracted electron beam from NINA and two magnetic spectrometers for coincidence detection of the electron and proton. Differential cross sections have been measured for isobar masses in the range 1.19–1.73 GeV/ c 2 .

STUDY OF A2 PRODUCTION IN THE REACTION PI- P ---> K0 K- P AT 50-GEV/C, 100-GEV/C, AND 175-GEV/C

Phys.Rev.D 27 (1983) 1-11, 1983.
Inspire Record 191493 DOI 10.17182/hepdata.23901

The reaction π−p→K0K−p has been measured from 50 to 175 GeV/c. The production characteristics of the A2 have been analyzed. We find spin and t dependence similar to lower energies, but the cross section falls rapidly with energy. In a Regge description of π−p→A2−p our data imply a rather small Pomeron-exchange component.

Highlights of the Reaction $\pi^- p \to \pi^- \pi^+ n$ at 100-{GeV}/$c$ and 175-{GeV}/$c$

Inspire Record 13822 DOI 10.17182/hepdata.33875

We present a summary of the physics results from an experimental study of the reaction π−p→π−π+n at 100 and 175 GeV/c incident-beam momentum. Our data show the continuing dominance of one-pion exchange in these reactions with the characteristic 1Plab2 momentum dependence. We extract the pion Regge trajectory from our data on π−p→ρ0n and study the zero structure of the ππ differential cross section up to sππ=12 GeV2.

STUDY OF K*- (890) AND K*- (1430) PRODUCTION IN THE REACTION K- P ---> ANTI-K0 PI- P AT 100-GEV/C AND 175-GEV/C

Bromberg, C. ; Dickey, J. ; Fox, G. ; et al.
Phys.Rev.D 29 (1984) 2469-2475, 1984.
Inspire Record 205297 DOI 10.17182/hepdata.23731

The reaction K−p→K¯0π−p has been studied at 100 and 175 GeV/c and the reaction π−p→K0K−p at 50, 100, and 175 GeV/c. Both reactions are dominated by production of resonances, K*(890), K*(1430) and A2(1320), A2(2040), respectively. Production cross sections, t distributions, and decay-angular distributions are studied. Isoscalar natural-parity exchange is dominant. The energy dependence of the K* and A2 resonance production between 10 and 175 GeV/c is well described by a Regge-pole model. Our data on A2 corrects that in an earlier paper.
