Study of Inclusive Production of $\pi^\pm$ and Protons in $\bar{p} p$ Interactions at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Vlasov, E.V. ; Babintsev, V.V. ; Bumazhnov, V.A. ; et al.

Z.Phys.C 13 (1982) 95, 1982.

Inspire Record 176790 DOI 10.17182/hepdata.1191

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.

Direct electron pair production by 6.4-TeV S-32 emulsion interactions

Kamel, S. ;

Phys.Lett.B 368 (1996) 291-298, 1996.

Inspire Record 428062 DOI 10.17182/hepdata.28411

A search for direct electron pairs was performed at the 6.4 TeV 32 S emulsion interactions at CERN. A total of 81 directly produced electron pairs have been observed, with an average number per interaction of about two. The results have been analysed in the light of the predictions of quantum electrodynamical calculations. A simple interpretation for the extracted results based on the virtual mass distribution is presented. The experimental results are in partial agreement with the present theories. The virtual mass distribution does not show a 1/m behaviour.
