Neutron Fragmentation and Inclusive Charge Exchange in p d and pi+ d Interactions at 195-GeV/c

Eisenberg, Y. ; Haber, B. ; Hochman, D. ; et al.
Phys.Rev.Lett. 38 (1977) 108, 1977.
Inspire Record 109610 DOI 10.17182/hepdata.21024

An excess of negative particles and depletion of positive particles in the backward hemisphere (c.m. system) is observed in π+ and p interactions on neutron target. dσ−dy is compared with pp interactions and the difference is related to the slow-proton spectrum produced in the pn interactions. A neutron fragmentation component is observed and the inclusive charge-exchange probability at the nucleon vertex is found to be about 0.4.

Observation of High Mass electron-Positron Pairs Produced in Proton Proton Collisions at the CERN ISR

Busser, F.W. ; Camilleri, L. ; Di Lella, L. ; et al.
Phys.Lett.B 56 (1975) 482, 1975.
Inspire Record 99170 DOI 10.17182/hepdata.27858

In an experiment performed at the CERN Intersecting Storage Rings (ISR), 11 e + e − pairs of high invariant mass value (> 2.5 GeV/c 2 ) have been observed. Of these events, 9 can be interpreted as arising from the reaction p + p → J (3.1) + anything. the cross-section for this reaction is estimated and compared with the result obtained at lower centre-of-mass energies.
