Properties of charged particle multiplicities in anti-neutrino interactions of the CHORUS experiment

In this study, the charged particle multiplicity distribution produced in anti-neutrino interactions in nuclear emulsion is investigated in terms of the log-normal parametric model and KNO-G scaling for the first time. The results are based on the data collected by the CHORUS experiment in the ${\nu }_{\mu }$ beam from CERN SPS. The analysis of 369 ${\overline{\nu }}_{\mu }$ CC events showed that anti-neutrino charged-particle multiplicity data shape is well described by a log-normal distribution. Furthermore, KNO-G scaling has been successfully applied to the data and results confirm the validity of KNO-G scaling for the anti-neutrino interactions. Finally, results are presented in detail in the form of figures and tables.
