KNO scaling in the neutral pion multiplicity distributions for π−p interactions at 40 and 250 GeV/c

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 γ weights of 10000 events of π−p 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.
