Double Statistical Tensors for the Reaction p p --> Delta++ Delta0 in a Range of 5-GeV/c to 25-GeV/c

The Genoa-World Proton-Proton collaboration Caso, C. ; Girimonte, L. ;
Nuovo Cim.A 33 (1976) 671, 1976.
Inspire Record 3097 DOI 10.17182/hepdata.9285

The joint decay distribution for the reaction pp → Δ++Δ0 is described in terms of double statistical tensors, which were determined in a model-independent way using the World Proton-Proton Data Summary Tape. The statistical tensors were calculated in nontransversal and in transversal reference frames. The results are presented as a function of the proton laboratory momentum, covering the range from 5 to 25 GeV/c. Due to a lack of statistics, the values as a function of the four-momentum transfers were obtained by adding together data from different energies. Results are again given in several reference frames.

EXCLUSIVE ANNIHILATION PROCESSES IN 8.8-GEV ANTI-P P INTERACTIONS AND COMPARISONS BETWEEN ANTI-P P NONANNIHILATIONS AND P P INTERACTIONS

Inspire Record 158992 DOI 10.17182/hepdata.34487

We give cross sections for annihilation and non-annihilation reactions in p p interactions at 8.8 GeV. The non-annihilation data are compared with pp data from the same experiment. We compare data on resonance production and on the impact parameter structure of the final states in p p annihilation and non-annihilation and pp interactions. We investigate the charge structure of the 2 π + 2 π − π 0 final state, and find it consistent with a simple quark model.

Experimental study of four-prong events in proton proton interactions at 13.1 gev/c

Inspire Record 75410 DOI 10.17182/hepdata.33033

Approximately 21 000 four-prong pp interactions at 13.1 GeV/ c have been studied using the CERN 2m hydrogen bubble chamber. The following reactions have been analyzed pp→ppπ + π − (1) pp→ppπ + π − π 0 (2) pp→ppπ + π + π − (3) The Δ-production is the dominant feature. We also observed the pππ decay of the N ∗ (1470) and N ∗ (1690). The ϱis weakly produced in the three reactions. The η and the α are observed in the reaction (2) and the presence of a ω isobar is discussed. Then the kinematical characteristics of the final particles are described.

Measurement of the $p p$ Cross-sections in the Momentum Range 0.9-2.0 GeV/c

Shimizu, F. ; Kubota, Y. ; Koiso, H. ; et al.
Nucl.Phys.A 386 (1982) 571-588, 1982.
Inspire Record 11839 DOI 10.17182/hepdata.37042

The pp total, elastic, and all the inelastic cross sections were measured at 11 momenta in the range 0.9–2.0 GeV/c. No clear structure was observed in their momentum dependences. The momentum dependence of the total cross section agrees quite well with the result of a phase-shift analysis by Arndt. Our measurement of the ppπ 0 and pnπ + cross sections served to normalize the earlier systematic but relative and extrapolated measurements of these cross sections over a narrower momentum range. Calculations by König and Kroll based on a pion exchange model including the effect of an I = 1 dibaryon did not fit the single-pion production cross sections.

Production of the F0 Meson in the Double Pomeron Exchange Reaction $p p \to p p \pi^+ \pi^-$ at $\sqrt{s}=62$-{GeV}

The Ames-Bologna-CERN-Dortmund-Heidelberg-Warsaw collaboration Breakstone, A. ; Campanini, R. ; Crawley, H.B. ; et al.
Z.Phys.C 31 (1986) 185, 1986.
Inspire Record 227129 DOI 10.17182/hepdata.15893

Data are presented for the exclusive reaction pp → pp π+ π− at\(\sqrt s= 62GeV\) with two leading protons at large Feynman-x and a centrally produced π+;π− system. In this kinematical configuration one expects a substantial contribution from Double Pomeron Exchange, which is a potential source of glueballs. The experiment was performed at the CERN ISR using the Split Field Magnet spectrometer. In the mass range between 1,000 and 1,700 MeV/c2 the invariant mass distribution for the central π+;π− system exhibits a very significant signal for thef0(1270) and no other obvious resonant states.
