Results are presented on the inclusive production of π± mesons and protons in\(\bar p\)p interactions at an incident antiproton momentum of 32 GeV/c in the MIRABELLE bubble chamber, based on a sample of 55,000 inelastic events. The spectra of π+(π−) andp(\(\bar p\)) are separated in the whole kinematically admitted region of phase space by a statistical method. The semi-inclusive and inclusive cross sections and the main average characteristics of π andp production are calculated. The invariant differential cross sections are studied as functions of the Fevnman scaling variablex, the rapidity and the transverse momentum. Thex distribution of π± mesons in the proton fragmentation region does not show any significant contribution from quark exchange or annihilation processes. A possible contribution of hard quark scattering on mesons or baryons is observed for large transverse momenta.

Negative Pion Production in Proton Proton Interactions at 69-GeV/c

The French-Soviet collaboration Bumazhnov, V.A. ; Ermolov, P.F. ; Fenyuk, A.S. ; et al.
Phys.Lett.B 50 (1974) 283-286, 1974.
Inspire Record 89197 DOI 10.17182/hepdata.27949

Inclusive spectra of π − production for pp interactions are discussed at 69 GeV/ c both in the central and in the fragmentation region and are compared to data at lower and higher energies. The p T dependence of the invariant structure function is also analysed.

Inclusive Production of Charged Pions in K- p Interactions at 32-GeV/c

The French-Soviet & CERN-Soviet collaborations Faccini, M.L. ; Barloutaud, R. ; Berard, A. ; et al.
Nucl.Phys.B 127 (1977) 109, 1977.
Inspire Record 119612 DOI 10.17182/hepdata.35284

Results are presented on the inclusive π ± production in K − p interactions at 32.1 GeV/ c . The invariant longitudinal distributions have been calculated both for π + and π − in the backward c.m. hemisphere and extrapolated in the forward hemisphere under some physical assumptions. The inclusive cross sections for π + and π − amount to 32.9 ± 1.5 mb and 35.0 ± 0.7 mb respectively. The energy dependence of the inclusive pion production has been analyzed in the framework of Mueller-Regge phenomenology both in the proton fragmentation and in the central region.

pi+- Meson and Proton Production in Inclusive and Semiinclusive Processes in p p Interactions at 69-GeV/c. 2.

Nuovo Cim.A 40 (1977) 237, 1977.
Inspire Record 108611 DOI 10.17182/hepdata.9273

We present the inclusive and semi-inclusive production of protons, π+, π−, for the full range of kinematic variables, from 7850 inelastic interactions obtained in the 4.7 m liquid-hydrogen bubble chamber Mirabelle at the Serpukhov accelerator and with an incident proton beam of 69 GeV/c. We compare the data with those at other energies, and we give the results of different phenomenological fits.
