TL;DR
This paper investigates neutral pion fluctuations in proton-proton interactions at 50 GeV, revealing increased fluctuations at high multiplicity that may suggest approaching pion condensate conditions.
Contribution
It provides the first measurement of neutral pion number fluctuations at high multiplicity in pp interactions at 50 GeV, indicating potential signs of pion condensation.
Findings
Fluctuations increase when total particle number exceeds 22.
Measured scaled variance omega shows significant growth at high multiplicity.
Results suggest possible pion condensate formation at high pion multiplicity.
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.
