Neutral pion number fluctuations at high multiplicity in pp-interactions at 50 GeV

High Energy Physics - Experiment 2012-08-27 v2

Abstract

Neutral pion number N0 distributions for each total number of particles in event Ntot=Nch+N0 are obtained. The scaled variance of neutral pion fluctuations, omega=D/<N0>, is measured. The fluctuations increase at Ntot >22. According to quantum statistics models it may indicate for the approaching to pion condensate conditions for high pion multiplicity in the system.
