KNO Scaling in the Neutral Pion Multiplicity Distributions for pi^{-}-proton 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 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.Comment: 8pp LaTeX, 1 Postscript Figur

Remarks on Koba-Nielsen-Olesen Scaling

It is shown that there is a second properly normalized KNO scaling function, $nP_n(n/\bar n)=\varphi(z)$, which has certain advantages in the analysis of KNO scaling. First, the $nP_n$ are not influenced by the statistical and systematic uncertainties of $\bar n$ hence $\varphi(z)$ provides more selective power than the original KNO scaling function $\bar nP_n(n/\bar n)=\psi(z)$. Second, the new scaling function generates scale parameter $\sigma=1$ since it depends only on the combination of $z$ and the scale parameter of $\psi(z)$. An analysis of $\varphi(z)$ is given using $e^+e^-$ annihilation data for charged particle multiplicity distributions.Comment: 8 pages, Plain TeX, 1 figure using uufile
