Production of Gamma, Lambda0, K0(s) and anti-Lambda0 in p p Collisions at 102-GeV/c.

Chapman, J.W. ; Cooper, John W. ; Green, N. ; et al.
Phys.Lett.B 47 (1973) 465-468, 1973.
Inspire Record 81963 DOI 10.17182/hepdata.28029

We have measured cross section for γ , K S °, Λ and Λ production at 102 GeV/ c and find: σ ( γ ) = 170 ± 16 mb ., σ ( K S °) = 4.6 ± 0.5 mb ., σ ( Λ ) = 3.2 ± 0.4 mb ., and σ( Λ ) = 0.23 ± 0.10 mb. Both 〈 n π °〉 and 〈 n Ks °〉 appear to rise linearly with n - while the ratio 〈 n Ks °〉/〈 n π °〉 is approximately independent of n - . The integrated invariant cross section as a function of x as well as d σ /d y and d σ /d p T 2 are presented and compared with other data.

Cross-Sections and Charged Particle Multiplicities at 102-GeV/c and 405-GeV/c.

Bromberg, C. ; Chaney, D. ; Cohen, Daniel H. ; et al.
Phys.Rev.Lett. 31 (1973) 1563-1566, 1973.
Inspire Record 81962 DOI 10.17182/hepdata.21360

We have measured the total inelastic cross section (σinel) and charged-particle multiplicities obtained in pp collisions at 405 GeV/c. The data are from a preliminary 12 000-picture bubble-chamber exposure. We find σinel=32.8±1.0 mb; the low moments of the multiplicity distribution for negative particles are 〈n−〉=3.50±0.07, D−=2.37±0.05, f2−=2.1±0.2, and f3−=0.1±0.9. We also present updated results at 102 GeV/c.

Observation of High Mass electron-Positron Pairs Produced in Proton Proton Collisions at the CERN ISR

Busser, F.W. ; Camilleri, L. ; Di Lella, L. ; et al.
Phys.Lett.B 56 (1975) 482, 1975.
Inspire Record 99170 DOI 10.17182/hepdata.27858

In an experiment performed at the CERN Intersecting Storage Rings (ISR), 11 e + e − pairs of high invariant mass value (> 2.5 GeV/c 2 ) have been observed. Of these events, 9 can be interpreted as arising from the reaction p + p → J (3.1) + anything. the cross-section for this reaction is estimated and compared with the result obtained at lower centre-of-mass energies.

Experimental Results on Large Angle Elastic p p Scattering at the CERN ISR

Kwak, N. ; Lohrmann, E. ; Nagy, E. ; et al.
Phys.Lett.B 58 (1975) 233, 1975.
Inspire Record 99556 DOI 10.17182/hepdata.27800

New experimental results are presented on proton-proton elastic scattering at centre-of-mass energies s =23 GeV and s =62 GeV . The data are obtained using the Split Field Magnet detector at the CERN Intersecting Storage Rings. The absolute differential cross-sections show an energy-dependent behaviour. The position of the diffraction minimum changes from t =(−1.44±0.02)GeV 2 at 23 GeV to (−1.26±0.03)GeV 2 at 62 GeV. The cross-section at the second maximum is increasing with s . The connection of these observations with the hypothesis of “geometrical scaling” is discussed.

K0 and Lambda Production at the CERN ISR

Phys.Lett.B 61 (1976) 309-312, 1976.
Inspire Record 101076 DOI 10.17182/hepdata.5534

Transverse momentum distributions of λ o , λ o , and K o , produced in pp collisions at x = 0, have obtained at the CERN ISR. The K o yield is in agreement with published K + , K − results, obtained at this centre-of-mass energy (√ s ≈44 GeV). The results on λ o and λ o production obtained in this experiment are compared with results obtained at lower centre-of-mass energies.

A Study of Inclusive Spectra and Two Particle Correlations at Large Transverse Momentum

Nucl.Phys.B 106 (1976) 1-30, 1976.
Inspire Record 108294 DOI 10.17182/hepdata.8491

The inclusive production of π and η mesons at 90° from proton-proton collisions has been measured at the CERN ISR at centre-of-mass energies between 23.5 and 62.4 GeV. The momentum correlation of charged particles emitted together with a large transverse momentum pion has also been studied, using two magnetic spectrometers each centred at 90°.

A Measurement of the Cross-Section of the Reaction p p --> n Delta++ (1232) at ISR Energies

Kwak, N. ; Nagy, E. ; Regler, M. ; et al.
Phys.Lett.B 62 (1976) 359-362, 1976.
Inspire Record 108757 DOI 10.17182/hepdata.27678

A measurement of the cross section of the charge-exchange reaction pp→ Δ ++ (1232)n at √ s = 23, 31 and 45 GeV at the CERN-ISR is reported. The energy dependence continues to follow a power law p lab − n with n = 1.94 ± 0.03 indicating dominance of one-pion exchange at the lowest ISR energy; there is some evidence for deviation from this at the higher ISR energies.

Evidence for Dominant Vector Meson Production in Inelastic Proton Proton Collisions at 53-GeV Center-of-Mass Energy

Jancso, G. ; Albrow, M.G. ; Almehed, S. ; et al.
Nucl.Phys.B 124 (1977) 1-11, 1977.
Inspire Record 119346 DOI 10.17182/hepdata.35433

The Split Field Magnet facility at the CERN ISR has been used to measure inclusive resonance production in inelastic p-p collisions at a c.m. energy of 53 GeV. The mass spectrum of pairs of oppositely charged hadrons shows a strong correlation, which can be explained as a consequence of dominant vector meson production, accounting for more than 60% of all pions and kaons produced.

Study of Photons Produced Simultaneously with the J/psi Particles at the CERN Intersecting Storage Rings

Cobb, J.H. ; Iwata, S. ; Palmer, R.B. ; et al.
Phys.Lett.B 72 (1978) 497-499, 1978.
Inspire Record 122488 DOI 10.17182/hepdata.50369

As a part of the study of the inclusive production of electron pairs in pp collisions at the CERN Intersecting Storage Rings (ISR), a search has been performed for additional photons accompanying J/ψ particles. The results suggest that (43±21)% of the J/ψ's are produced via the photonic decay of one of the χ(3.5) states.
