PAIR PRODUCTION OF PIONS WITH SYMMETRIC MOMENTA IN THE RANGE 0.5-GeV/c <= P(T) <= 2.0-GeV/c in 70-GeV p p COLLISIONS

Abramov, V.V. ; Baldin, B.Yu. ; Buzulutskov, A.F. ; et al.

Inspire Record 169450 DOI 10.17182/hepdata.41219

The invariant cross-section slope of the pp→ π + π − +X process as a function of p T is found to have a break near 1 GeV/ c . Fitting the cross section by a sum of two exponents gives the values of powers (12.3±0.9)(GeV/ c ) −1 and (8.7±0.6)(GeV/ c ) −1 . The experimental points at p T ⩾1 GeV/ c are significantly higher than predictions based on hard scattering models such as QCD and CIM.

CHARGED PARTICLE AND PI0 MULTIPLICITY DISTRIBUTIONS AND THE ANNIHILATION PROPERTIES OF ANTI-P P INTERACTIONS AT 70-GeV/c

Dumont, J.J. ; Lemonne, J. ; Vanhomwegen, G. ; et al.
Z.Phys.C 13 (1982) 1-9, 1982.
Inspire Record 179759 DOI 10.17182/hepdata.16433

The elastic and inelastic\(\bar p\)p cross sections at 70 GeV/c have been determined in an experiment performed at CERN using BEBC equipped with a TST. The topological cross sections were measured and the moments of the inelastic multiplicity distribution are 〈nc〉=6.16±0.09, 〈nc〉/D=2.04±0.05 andf2cc=2.97±0.03. The average number of Dalitz pairs per inelastic event is (3.12±0.09)×10−2. Assuming that these all arise from π0 decay the average π0 multiplicity is\(\langle n_{\pi ^0 } \rangle= 2.71 \pm 0.14\). The\(\bar p\)p−pp cross section differences lead to an annihilation cross section σA = 4.42±0.41 mb and the moments of the annihilation multiplicty distribution are 〈nA〉=8.0±0.3, 〈nA〉/D=2.5±0.2 andf2A−−=−1.4±0.3. An independent check of σA was made by investigating fast forward charged and neutral secondary interactions in the TST and in the surrounding neon-hydrogen mixture, and gives a value σA = 5.0±1.6 mb. The ratio of fast\(\bar n\) to\(\bar p\) production in non-annihilation interactions at 70 GeV/c is found to be 0.45±0.11.

Energy and Quantum Number Flow in $K^+ p$ and $\pi^+ p$ Interactions at 32-{GeV}/$c$ and 70-{GeV}/$c$

The Brussels-Serpukhov-Tbilisi-Genoa-Mons-Nijmegen-CERN collaboration Azhinenko, I.V. ; Belokopytov, Yu.A. ; Vorobev, A.P. ; et al.
Z.Phys.C 16 (1983) 291, 1983.
Inspire Record 181635 DOI 10.17182/hepdata.10881

Energy, charge and strangeness flow inK+p interactions at 32 and 70 GeV/c, and π+p interactions at 32 GeV/c are studied in terms of the angular variable λ=|x|/pT. The data ondQ/dλ anddE/dλ show only a weak indication of scale breaking between 32 and 70 GeV/c. For inclusive “non-diffractive”, inclusive “diffractive” and exclusive “non-diffractive” jets, the fraction of charge in any angular region ΔΩ away from the central region is found to be proportional to the energy fraction in the same interval. The data ondQ/dE versus λ are compatible with some versions of dual-sheet models and agree also with the LUND Monte-Carlo model. The data are also compared with\(v(\bar v)p\) interactions in BEBC. In exclusive channels the average ratiodQ/dS=0.78±0.04 is consistent, in the framework of fragmentation models, with a larger probability for the fragmentation of the\(\bar s\)-valence quark than theu-valence quark in theK+-meson.

INCLUSIVE PRODUCTION OF NEUTRAL STRANGE PARTICLES IN ANTI-P P INTERACTIONS AT 70-GeV/c

Lemonne, J. ; Vanhomwegen, G. ; Wickens, J. ; et al.
Z.Phys.C 24 (1984) 103-110, 1984.
Inspire Record 207327 DOI 10.17182/hepdata.16319

The inclusive production ofKs0, Λ and\(\bar \Lambda \) particles is investigated in 70 GeV/c\(\bar pp\) interactions in an experiment performed at CERN using BEBC equipped with a TST. Differential cross-sections are studied and compared with corresponding data at surrounding energies. Differences withpp data obtained at the same energy allow an estimate of theKs0, production cross-section in annihilation processes. Evidence is also given for central\(\Lambda \bar \Lambda \) production.
