KNO scaling was put forward by Koba, Nielsen, and Olesen (KNO) in 1972. Although it is an important tool for explaining multiplicity distributions and formulated for the asymptotic energies, it has been applied at a finite energy range where its formulation is not self-consistent. A consistent generalization, known as KNO-G scaling, was done by Golokhvastov in 1977 to make it self-consistent. Then, KNO-G scaling has been successfully applied in many experiments and its validity has been reported. In this study, KNO-G scaling is tested in neutrino interactions. The charged hadron multiplicity of CHORUS, OPERA, NOMAD and DONUT, which are neutrino experiments, is compared and tested the KNO-G scaling. It is observed that neutrino data are consistent with KNO-G scaling. A fit is superimposed on the data sets and fit parameters are compared.

The OPERA experiment reached its main goal by proving the appearance of [Formula: see text] in the CNGS [Formula: see text] beam. Five [Formula: see text] candidates fulfilling the analysis defined in the proposal were detected with a S/B ratio of about ten allowing to reject the null hypothesis at 5.1[Formula: see text]. The search has been extended by loosening the selection criteria in order to obtain a statistically enhanced, lower purity, signal sample. One such interesting neutrino interaction with a double vertex topology having a high probability of being a [Formula: see text] interaction with charm production is reported. Based on the enlarged data sample the estimation of [Formula: see text][Formula: see text] in appearance mode is presented. The search for [Formula: see text] interactions has been extended over the full data set with a more than twofold increase in statistics with respect to published data. The analysis of the [Formula: see text] channel is updated and the implications of the electron neutrino sample in the framework of the 3+1 neutrino model is discussed. An analysis of [Formula: see text] interactions in the framework of the sterile neutrino model has also been performed. Finally, the results of the study of charged hadron multiplicity distributions is presented.

Remarkable Agreement

The semiempirical formulation of Ghosh et al. for the energy dependence of multiplicity in hadronic collisions has been applied to account for the experimental multiplicity data of π±p and K±p collisions. A remarkable agreement has been found over the entire energy range.

Volume Fluctuations

Recent preliminary results on multiplicity fluctuations in p+p, Be+Be and Ar+Sc collisions from the NA61/SHINE collaboration are presented. The scaled variance of charged hadron multiplicity changes little when going from p+p to Be+Be collisions and drops dramatically from Be+Be to Ar+Sc interactions. The centrality selection procedure and the influence of volume fluctuations are discussed. Comparisons with the EPOS event generator are shown.
