Production of Charged Pions at High Transverse Momentum in $p p$ Collisions at $\sqrt{s}=45$-{GeV} and 62-{GeV}

Phys.Lett.B 135 (1984) 505-509, 1984.
Inspire Record 193699 DOI 10.17182/hepdata.30594

We report on measurements of charged pion production cross sections at θ ≅ 50°, p T ≅ 3–9 GeV / c and √ s = 45 GeV , taken with the Split Field Magnet Detector at the CERN Intersecting Storage Rings (ISR). Together with previous data at √ s = 62 GeV , this allows the calculation of the exponent n assuming a power law dependence p n T . Values of n ≈ 8 are found at low x T = 2 p T /√ s which drop to about 7 at x T ≈ 0.3. The measured values of π + /π − rise with x T and approach ≈ 2 at x T ≈ 0.3. A first-order QCD calculations is reasonably consistent with the data.

Inclusive Photoproduction of Neutral Strange Particles at 20-{GeV}

The SLAC Hybrid Facility Photon collaboration Abe, K. ; Bacon, T.C. ; Ballam, Joseph ; et al.
Phys.Rev.D 29 (1984) 1877, 1984.
Inspire Record 190724 DOI 10.17182/hepdata.23774

We have studied inclusive production of KS0, Λ, and Λ¯ particles in 20-GeV γp interactions and have found features similar to those observed in both hadronic and leptonic interactions. The production cross sections, charged-particle multiplicities, and average Λ polarization are reported. Inclusive distributions of x and pT are shown and discussed in terms of quark fragmentation models. Production cross sections for K*(890) and Σ*(1385) are also reported.

Comparison of Inclusive Distributions in $p p$ and $\bar{p} p$ Interactions at $\sqrt{s}=53$-{GeV}

Inspire Record 191414 DOI 10.17182/hepdata.30631

Measurements are presented of inclusive distributions in pp and p p interactions at √ s = 53 GeV. The data were obtained at the CERN ISR using the Split Field Magnet spectrometer with a minimum bias trigger. The inclusive distributions are analyzed as functions of the transverse momentum, the rapidity and the Feynman- x variable.

The Production of High Momentum Particles and Resonances in $p p$ Collisions at the {CERN} Intersecting Storage Rings

Inspire Record 181613 DOI 10.17182/hepdata.33961

Data are reported on the momentum distributions of Λ, Λ (1520), φ (1020), Λ and p , inclusively produced between 1° and 2° with respect to one of the primary proton beams at the CERN Intersecting Storage Rings. In addition, the decay angular distribution of the Λ(1520), the ratio of the cross sections for the production of Σ − (1385) and Σ + (1385) and the ratios among different charge states of the pairs Λπ , Λ K, Δ ++ (1232) π and ππ have been measured. These data are confronted with current ideas on fragmentation.

The inclusive cross section for the production ofKs0 mesons, Λ and\(\bar \Lambda\) particles in proton-proton interactions at\(\sqrt s= 63\) GeV is presented. The produced particles have been detected in the full phase space. Behaviour of the longitudinal and transversal depandences of the cross sections are discussed. The total production cross sections fors0 mesons and Λ particles was determined to\(\sigma _{{\rm K}_S^0 }= (25.5 \pm 1.4)\) mb andσΛ=(7.8±1.2) mb respectively. A strong energy dependence of the production cross sections is observed.

Inclusive and Semiinclusive $\rho^0$ Production in $\pi^+ / \pi^- / K^+ / P P$ Interactions at 147-{GeV}/$c$

Inspire Record 170594 DOI 10.17182/hepdata.1419

In an experiment with the 30-inch Hybrid Spectrometer at Fermilab we have obtained the inclusive and semi-inclusive production cross sections of the ϱ0 meson using a conventional background subtraction technique. Production cross sections for the ϱ0 are derived as a function of the Feynman scaling variablex, and the transverse variablespt2 andEt=(pt2+M2)1/2. The longitudinal distributions are compared with the (1−x) dependence of the proton and meson valence quark structure functions, using various forms of recombination and fragmentation models. The transverse distributions are compared with thermodynamic models. We give density matrix elements for the ϱ0 production from pions in the extreme forward region.

New results on the inclusive and semi-inclusive production of π + mesons and protons in the whole phase space are given for about 2.2 · 10 4 inelastic p p interactions at 22.4 GeV/ c . A method of statistical separation for spectra of particles of the same charge which are produced in CP -symmetrical reactions is discussed in detail. Experimental data are compared with quark-parton model predictions.
