New Results on Nucleon Double Diffraction at the {CERN} {ISR}

Goggi, G. ; Cavalli-Sforza, M. ; Conta, C. ; et al.
Phys.Lett.B 79 (1978) 165-169, 1978.
Inspire Record 131629 DOI 10.17182/hepdata.27380

Results on exclusive double diffraction dissociation in (N π ) and (N ππ ) final states are reported for neutron-neutron interactions at √ s = 26.4 GeV and for the proton-neutron interactions at √ s = 37.2 GeV. The data have been obtained at the CERN intersecting storage rings using split field magnet detector with proton-deuteron and deuteron-deuteron colliding beams. Factorization is shown to be verified to a very high degree in both mass- and t -differential cross-sections. The data confirm the previously observed rise in the proton-proton double diffractive cross-section as a function of c.m. energy.

Results of two spark chamber experiments on A 2 − production in the reaction π − p → K − K S 0 (→ π + π − )p at 9.8 and 18.8 GeV are presented. Decay angular distributions and differential cross sections are given, and the energy dependence of the cross section σ [ π − p → A 2 − (→ K − K 0 )p] is compared with results from π − p → A 2 − (→ 3 π )p.

Analysis of the Charge Exchange Reaction $p p \to (p \pi^+$) ($p \pi^-$) and of $\Delta^{++}$ Delta0 Production at the {CERN} {ISR}

Nucl.Phys.B 143 (1978) 365-394, 1978.
Inspire Record 131628 DOI 10.17182/hepdata.34885

We present the results of a systematic analysis of charge-exchange double dissociation in proton-proton collisions at the CERN Intersecting Storage Rings. The data, obtained with the Split-Field Magnet detector, cover the entire ISR energy range between s = 23 GeV and s = 63 GeV at five standard energies.

Inclusive Electroproduction From Protons and Deuterons

Martin, J.F. ; Feldman, G.J. ; Hanson, G. ; et al.
Phys.Rev.D 20 (1979) 5, 1979.
Inspire Record 131005 DOI 10.17182/hepdata.24206

We present results on the inclusive distributions of final-state hadrons created in deep-inelastic electron scattering from protons and deuterons. Data were taken from all portions of the kinematic range simultaneously in an apparatus which had equal detection efficiency for both charge signs. A subset of the produced hadrons were identified with a threshold-type Čerenkov counter. We find that the charge ratio h+h− is a strong function of Q2, xF, and pT2, with little dependence on s. The ratio of production of h− from deuterium to that from hydrogen as a function of φ is flat. The invariant cross section for each charge sign and each target exhibits the seagull effect (a correlation in 〈pT〉 and 〈xF〉). The value of 〈pT〉 for data in the range 0.4

Inclusive $\gamma$ and $\pi^0$ Production in $e^+ e^-$ Annihilation

Scharre, D.L. ; Fong, A. ; Pun, T. ; et al.
Phys.Rev.Lett. 41 (1978) 1005, 1978.
Inspire Record 130859 DOI 10.17182/hepdata.20888

We have measured inclusive γ and π0 production in multiprong events produced by e+e− annihilation in the center-of-mass energy range 4.9 to 7.4 GeV. We find the π0 inclusive cross section to be consistent in shape and normalization with half the charged-π cross section between x=0.15 and 0.60, with an integrated inclusive cross-section ratio of σ(π0)|σ(π+)+σ(π−)|=0.47±0.10.

Observation of the $D$, $e$ and Delta Mesons in $\pi^- p$ Interactions at 12-{GeV}/$c$ and 15-{GeV}/$c$

We have observed the D(1285), E(1420) and δ(975) mesons produced in 12 and 15 GeV/ c π − p interactions at the CERN Omega Spectrometer. Production cross sections and decay branching ratios are presented. Analysis of the decay D(1285) → δ (975) π favours a spin-parity assignment of 1 + .

Inclusive $\pi^+$ to $\pi^-$ Ratios and Quark Distributions of Pions and Nucleons

Eisenberg, Y. ; Haber, B. ; Hochman, D. ; et al.
Phys.Lett.B 83 (1979) 127, 1979.
Inspire Record 131271 DOI 10.17182/hepdata.27334

The ratio R of inclusive π + π − production at low transverse momenta is measured in π + n and pn interactions at 195 GeV/ c . R ( 1 R ) in the proton (neutron) fragmentation region increases with Feynman- x and is smaller than R from π + fragmentation. The results agree with a quark-quark scattering model originally proposed for “hard” processes and disagree with a modified version of the model which includes gluon scattering.

Precision Measurement of Proton Proton Total Cross-section at the {CERN} Intersecting Storage Rings

Amaldi, U. ; Cocconi, G. ; Diddens, A.N. ; et al.
Nucl.Phys.B 145 (1978) 367-401, 1978.
Inspire Record 131412 DOI 10.17182/hepdata.34944

The measurement of the proton-proton total cross section performed by the CERN-Pisa-Rome-Stony Brook Collaboration at the CERN ISR is discussed in detail. The total interaction rate, the elastic scattering rate in the forward direction, and the machine luminosity were measured simultaneously to obtain three different determinations of the total cross section. Consistent results were found, which made it possible to prove the reliability of the Van der Meer luminosity calibration within +-0.9% and to achieve a precision of +-0.6% in the measurement of the total cross section.
