Description

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