Résumé : First results from the UA5 detector on charged particle production at √s = 540 GeV in the pseudorapidity range {divides}ν{divides} < 5 are presented. The central region pseudorapidity density is 3.0 ± 0.1 for non-diffractive events. The central width of the observed ν-distribution is narrower than expected from a simple extrapolation of ISR data,suggesting an increase in the mean pt for hadron production. © 1981.
