Description

SHIP is a new general purpose fixed target facility, whose Technical Proposal has been recently submitted to the CERN SPS Committee. In its initial phase, the 400GeV proton beam extracted from the SPS will be dumped on a heavy target with the aim of integrating $2\times 10^{20}$ pot in 5 years. A dedicated detector downstream the target will allow to probe a variety of models with light long-lived exotic particles and masses below a few GeV/c$^2$. Another dedicated detector will allow the study of neutrino cross-sections and angular distributions, and it will be the focus of the talk. $\nu_\tau$ deep inelastic scattering cross sections will be measured with a statistics 1000 times larger than currently available, with the extraction of the $F_4$ and $F_5$ structure functions, never measured so far. Moreover, $\nu_\tau$'s will be distinguished from $\bar{\nu}_\tau$'s, thus providing the first observation of the $\bar{\nu}_\tau$. With $\nu_\mu$ scattering it will be possible to reduce by about $50\%$ the current uncertainty on the strange content of the nucleon in the range of the x variable between 0.05 and 0.3. Eventually, it will be possible to improve existing limits on dark photons decaying into dark matter particles, with the elastic scattering of these ones on electrons. The detector will be based on several techniques developed for the OPERA experiment at LNGS.
