Abstract:
The DsTau experiment at CERN-SPS has been proposed to measure an inclusive differential cross-section of a Ds production with a consecutive decay to tau lepton in p-A interactions. A precise measurement of the tau neutrino cross section would enable a search for new physics effects such as testing the Lepton Universality (LU) of Standard Model in neutrino interactions. The detector is based on nuclear emulsion providing a sub-micron spatial resolution for the detection of short length and small “kink” decays. Therefore, it is very suitable to search for peculiar decay topologies (“double kink”) of Ds→τ→X. The physics run in 2021 was successfully done and the emulsion films are ready for scanning and analysis. In this presentation, the momentum measurement of charged particles through MCS, as well as a comparison between Monte Carlo momentum and momentum estimated with follow down track analysis for simulated particles are presented.
