Description
The DsTau (NA65) experiment at CERN is designed to measure the inclusive differential cross section for the production of Ds mesons decaying into a tau lepton and a tau neutrino in proton–nucleus (p–A) interactions. The DsTau detector is based on the nuclear emulsion technique, which provides exceptional spatial resolution and enables the precise detection of short-lived particles such as charmed hadrons. In this presentation, we present the first results from the analysis of the pilot-run data, with a particular emphasis on the performance of proton interaction vertex reconstruction in environments with high track densities. The collected data have been compared with predictions from several Monte Carlo event generators. The current status of the Ds search is also reported.
