| Abstract | The Standard Model consists of three generations of leptons, with the neutrinos corresponding to each generation being extensively studied and well understood, except for the tau neutrino ($\nu_{\tau}$). While the interaction of the $\nu_{\tau}$ has been observed and its cross section measured in a few experiments, the number of observed interactions remains limited and is accompanied by significant uncertainties. The DsTau (NA65) experiment at CERN-SPS aims to measure the cross-section of $D_{s}$ meson production, which will provide a precise understanding of the $\nu_{\tau}$ production. The DsTau experiment employs a nuclear emulsion-based detector with a sub-micron spatial resolution to capture the small kink in the $D_{s} \rightarrow \tau$ decay topology. In this thesis, we present the first results of the data analysis of the 2018 run. A new method is developed for the proton track reconstruction through the full detector. The proton interaction vertex is analyzed in detail, and data are compared with different Monte Carlo event generator predictions. The findings presented in this study can be utilized to improve the predictions of event generators. |
