Factorial correlators from π+p and K +p collisions at 250 GeV/c

Abstract

Factorial correlators are studied in 250 GeV/c π +p and K +p collisions as a function of the distance in rapidity. The correlators are found to increase with decreasing correlation distance, independently of the rapidity resolution. The increase approximately follows a power law, but the power is considerably larger than expected from a log-normal approximation in the simple α model of intermittency. Also the FRITIOF results are independent of the resolution, but slopes and p T behavior cannot be reproduced by this model.
