Remarks on Koba-Nielsen-Olesen ScalingDOI: 10.1016/0370-2693(94)91418-4 Abstract: 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.
