Abstract
Research for new physics is currently one of the main tasks of particle physics, looking for new particles having high masses (energy frontier) or very feebly interacting (intensity frontier). The SHiP experiment has been proposed in 2015 to search for hidden particles at the intensity frontier. It is designed to be located in a new beam dump facility, receiving 400 GeV protons from the CERN SPS accelerator. A total of $2 \times 10^{20}$ protons on target is expected to be collected in five years of data taking. The experiment plans to explore a wide domains of couplings and masses for light long-lived exotic particles. Their decays in a 50 m long vacuum vessel can be reconstructed in a background free environment, allowing for a high sensitivity of the experiment. Moreover, the experiment is suitable to reconstruct tau neutrino interactions, with expected yields orders of magnitude larger than previous experiments. This provides interesting possibilities of study such as the first observation of $\bar{\nu}_\tau$, the measurement of $\nu_\tau$ and $\bar{\nu}_\tau$ cross-sections with high statistics and the exploration of the charm content of the nucleon. Ancillary measurements to validate the Monte Carlo predictions have been performed in July 2018, and their analysis is currently
ongoing.
