First results on complete events from p overlinep collisions at the cm energy of 540 GeV.
Abstract
First results from the UA5 detector on charged particle production at √ s = 540 GeV in the pseudorapidity range ∣ ν∣ < 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.
