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

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.

High $p_T K^\pm / \pi^\pm$ Production in $p p$ Collisions at the {ISR}: Strangeness Suppression and Gluon Effects

The ratios of high p T charged kaon to pion production cross sections at √ s = 45 and 62 GeV are presented. The values of the K ± π ± ratios are essentially independent of both √ s and x T = 2p T √s and are compatible with a strangeness suppression factor λ = 0.55. By contrast, the K − π − values fall with x T suggesting a gluonic origin of K − . QCD calculations agrees with the measurements.

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

The Ames-Bologna-CERN-Dortmund-Heidelberg-Warsaw collaboration Breakstone, A. ; Campanini, R. ; Crawley, H.B. ; et al.
Phys.Lett.B 132 (1983) 458-462, 1983.

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.
