The DsTau (NA65) experiment at CERN was proposed to measure an inclusive differential cross-section of Ds production in p-A interactions. As this process is a main source of tau neutrino production, its study is necessary for a measurement of the tau neutrino interaction cross-section which, in turn, enables a search for new physics effects such as testing the Lepton Flavour Universality of the Standard Model in the neutrino interactions. The DsTau detector is based on the nuclear emulsion technique providing an excellent spatial resolution providing a very high spatial resolution for detecting short-lived particles like charmed hadrons. A high precision in vertex reconstruction allows one to measure charged particle multiplicities accurately in a high track density environment. In this paper, the preliminary results of the analysis of the pilot run data are presented.
