Theπ0 andη0 production is studied inπ−p interactions at 360 GeV/c. The cross section forπ0 production in the forward hemisphere (X>0) isσ(π0)=(49.7 ± 1.0 ± 1.1) mb and for η withX>0.1,Nch>2,σ(η0)=(3.1 ± 0.5) mb. The ratio of theπ0 toη0 cross section forX>0.1,Nch>2 isσ(π0)/σ(η0). Results on FeynmanX andpT distributions are presented. The data were obtained using the European Hybrid Spectrometer EHS and the bubble chamber LEBC at CERN.

Inclusive $\pi^0$ Production in 250-{GeV}/$c \pi^- p$ Interactions

Diamond, R.N. ; Hagopian, S. ; Hays, P.J. ; et al.

Phys.Rev.D 25 (1982) 41, 1982.

Inspire Record 11137 DOI 10.17182/hepdata.23973

Neutral-pion production in 250-GeV/c π−p interactions are studied using the Fermilab 15-ft bubble chamber. The mean number of neutral pions produced is 3.54±0.15 per inelastic collision and a fit to a linear dependence on the charged multiplicity gives 〈n0〉=1.30+0.56n−. The π0 transverse- and longitudinal-momentum distributions are obtained from the inclusive γ-ray data and compared with the distribution obtained from those π0's which have both decay γ rays converting in the bubble chamber.

Production of Charged Hadrons, $\pi^0$ and Electron Pairs in 70-{GeV}/$c \pi^- p$ Interactions

The Bologna-Glasgow-Rutherford-Saclay-Turin collaboration Barloutaud, R. ; Baruzzi, V. ; Bird, I. ; et al.

Nucl.Phys.B 176 (1980) 285-302, 1980.

Inspire Record 153174 DOI 10.17182/hepdata.34414

Charged multiplicity and π 0 cross sections for π − p inelastic interactions at 70 GeV/ c are presented. The data were obtained from an exposure of the BEBC bubble chamber equipped with a track sensitive target (TST) to an unseparated negative beam at the CERN SPS. About 10 000 events were used for the charged multiplicity study, and about 2000 Dalitz pairs for the π 0 production analysis. A total of 12 e + e − pairs with a mass higher than the π 0 mass were found and analysed in terms of η or ω Dalitz pairs or decay pairs of vector mesons. Comparisons with data at other energies are made in terms of charged prong, π 0 cross sections, and of multiplicity parameters. The moments of longitudinal and transverse momentum distributions of the π 0 are determined and compared to the predictions of quark counting rule models.

Inclusive Production of $\pi^0$, $\K^0$(s), $\Lambda^0$, and Anti-lambda0 in 100-{GeV}/c, 200-{GeV}/c and 360-{GeV}/c $\pi^- p$ Interactions

Nucl.Phys.B 167 (1980) 41-60, 1980.

Inspire Record 8802 DOI 10.17182/hepdata.34519

Inclusive cross sections for π 0 , K s 0 , Λ 0 and Λ 0 production in 100, 200 and 360 GeV /c π − p interactions are presented and compared with data at other energies. Invariant cross sections for γ, K s 0 , Λ 0 and Λ 0 production are presented in terms of Feynman x , the rapidity y , and transverse momentum squared, p T 2 . A comparison of the observed γ spectrum is made with the spectra computed assuming that the π 0 momentum distribution is identical to that of the observed π + or π − .
