Phys.Lett.B 44 (1973) 521-526, 1973.
Inspire Record 85256 DOI 10.17182/hepdata.28095

The inclusive production al all charged particles of transverse momentum p T between 1.5 and 4.4 GeV/ c at centre of mass angles 90° and 59.4° from p-p-collisions with √ s = 44 and 53 GeV has been measured. No strong energy dependence is observed for these transverse momenta.

Production of $\gamma, \Lambda^0, K^0_s$ and $\bar \Lambda^0$ in pp 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.

Charged particle productions at 90 degrees in the center-of-mass in very high energy proton proton collisions

Banner, M. ; Hamel, J.L. ; Pansart, J.P. ; et al.
Phys.Lett.B 41 (1972) 547-551, 1972.
Inspire Record 85071 DOI 10.17182/hepdata.28219

The transverse momentum distribution at 90° of pions, protons and antiprotons have been measured at the CERN intersecting storage rings for C.M. energies between 23.2 and 52.7 GeV. In this energy range, the pion and proton distributions are almost energy independent. The antiproton production rises by a factor of two between 23.2 and 52.7 GeV.

The inclusive single-particle spectra of pi-, K0(s) and Lambda in proton proton collisions at 19-GeV/c

The Scandinavian Bubble Chamber collaboration Boeggild, H. ; Dahl-Jensen, E. ; Hansen, K.H. ; et al.
Nucl.Phys.B 57 (1973) 77-99, 1973.
Inspire Record 84068 DOI 10.17182/hepdata.32535

Data on the inclusive production spectra of K S 0 and Λ from proton-proton collisions at 19 GeV are presented and discussed in connection with the earlier studied inclusive π − production spectrum. The three single-particle spectra are compared with a crude two-center thermal model for the average radiation from the pp collisions.

Study of anti-p p ---> lambda(sigma0) anything at 5.7 gev/c

Ganguli, S.N. ; Sadoulet, B. ;
Nucl.Phys.B 53 (1973) 458-472, 1973.
Inspire Record 84214 DOI 10.17182/hepdata.32591

We present a study of the incclusive reaction p p → Λ/Σ 0 + anything at 5.7 GeV/ c based on 9544 events. The main experimental feature is a flattening of the momentum-transfer distribution with the increasing missing mass. We attempt to interpret the results in the framework of the triple-Regge limit. The effective trajectory is shown to be in good agreement, within theoretical uncertainties, with what is expected from K or K ∗ – K ∗∗ exchanges.

High-energy proton scattering on nuclei

Klovning, A. ; Kofoed-Hansen, O. ; Schluepmann, K. ;
Nucl.Phys.B 54 (1973) 29-41, 1973.
Inspire Record 84178 DOI 10.17182/hepdata.32651

We have studied high-energy proton scattering on Be, C, Cu and Pb targets using a single-arm spectrometer. The projectile momenta were 19 and 24 GeV/ c , the square of the four-momentum transfer varied from t = 0.1 to t = 4.4 GeV 2 . We have recorded momentum distributions of scattered protons in the high-momentum range. An application of multiple-scattering theory yielded agreement of calculation and experimental results to within a ± 30% uncertainty of the former.

Phys.Lett.B 46 (1973) 471-476, 1973.
Inspire Record 83673 DOI 10.17182/hepdata.28041

Invariant cross-sections are presented for the inclusive reaction p + p → π o + anything, Measurements of large transverse momentum π o 's (2.5 GeV/ c < p ⊥ <9 GeV/ c ) were made near 90° at the CERN ISR at five centre-of-mass energies (√ s = 23.5, 30.6, 44.8, 52.7 and 62.4 GeV. At large p ⊥ , the invariant cross-sections are seem to vary with s and p ⊥ , in good agreement with a fit of the form Ap ⊥ − n F ( p ⊥ /√ s ), with n ≈8 and F ( p ⊥ /√ s )≈ exp (−26 p ⊥ /√ s ).

A formation study of n anti-n interactions between 1.09 and 3.45 gev/c. ii. strange particles

Oh, B.Y. ; Eastman, P.S. ; Ming, Ma.Z. ; et al.
Nucl.Phys.B 51 (1973) 57-76, 1973.
Inspire Record 84294 DOI 10.17182/hepdata.8011

A systematic study of p p and p d reactions producing strange particles between 1.09 and 3.45 GeV/ c has been completed. Reaction and resonance cross-section data are presented at 11 p p and 13 p d momentum settings. Evidence for a broad shoulder in the K K 3π final state near 1.8 GeV/ c is presented and contrasted to previously published work on a portion of the final data sample. No evidence for a p n → K 0 K − ω effect near 1.3 GeV/ c is found, ruling out an association of K K ω effects with the nearby isospin one enhancement in the total cross section. Finally, we find no evidence for a p p → K K ω enhancement near 1.8 GeV/ c .

Cross sections of common final states for K- p interactions at 8.25-GeV/c

The Athens-Democritus-Liverpool-Vienna collaboration Fry, J.R. ; Brankin, C. ; Matthews, R. ; et al.
Nucl.Phys.B 58 (1973) 408-419, 1973.
Inspire Record 83983 DOI 10.17182/hepdata.8005

Topological and channel cross sections are given for the more common final states produced in K − p interactions at 8.25 GeV/ c together with the single particle inclusive cross sections. We present cross sections for prominent resonances occurring in final states K N (nπ) and find the resonance fractions to be roughly independent of multiplicity.
