KNO Scaling in the Neutral Pion Multiplicity Distributions for pi^{-}-proton interactions at 40 and 250 GeV/c

TL;DR

This paper investigates the scaling behavior of neutral pion multiplicity distributions in pi-minus proton interactions at 40 and 250 GeV/c, using a model-independent analysis of multiplicity moments and comparing different theoretical models.

Contribution

It introduces an extension of the generating functional technique to analyze detection losses in multiplicity moments for pion interactions.

Findings

Observed KNO scaling in neutral pion multiplicity distributions.

Compared data with FRITIOF and shifted KW models, finding good agreement.

Demonstrated the effectiveness of the extended generating functional method.

Abstract

We analysed the binomial multiplicity moments of the neutral pions, using an extension of the generating functional technique for detection losses. We applied this model-independent method to the individual gamma-weights of 10000 events of pi^{-}-proton interactions at 40 GeV/c. We compared the obtained results to those of 250 GeV/c. We used the FRITIOF and a shifted KW distribution to describe the data.
