Intermittency studies in pp collisions at ✓s = 630 GeV

Abstract A significant intermittency signal is observed in 630 GeV p p collisions measured in the UA1 central detector. It occurs with similar magnitude in different variables: pseudorapidity, rapidity and azimuthal angle. The signal increases with decreasing charged particle multiplicity in the event. Its strength in a sample of low p ⊥ tracks and its multiplicity dependence are not reproduced by commonly used Monte Carlo models of high energy interactions.
