Description

A previously reported observation of electrons produced in proton-proton collisions at the CERN ISR has been extended to 5 different centre-of-mass energies (√s=23.5, 30.6, 44.8, 52.7 and 62.4GeV). The apparatus detected electrons with transverse momenta, greater than 1.0GeV/c. The ratio of the electron to pion cross sections in the kinematic region studied is approximately 10-4. The momentum spectrum and particle composition of particles emitted with ΔPHI approximately 180 deg relative to the electrons are found to be similar to those emitted with pions

Abstract (French)

On a etendu l'observation des electrons produits dans les collisions proton-proton aux ISR du CERN (resultats deja rapportes) a cinq energies differentes dans le centre de masse (√s=23,5; 30,6; 44,8; 52,7; et 62,4 GeV). L'appareillage detectait les electrons de moment transversal superieur a 1,0GeV/c. Le rapport des sections efficaces de l'electron a celles du pion dans la region cinematique etudiee est approximativement 10-4. Le spectre d'impulsion et la composition particulaire de l'emission relative aux electrons (avec Δ PHI voisin de 180 deg) sont semblables a ceux obtenus avec les pions
