Neutrino Physics within the SHiP Experiment — •Caren Hagner, Daniel Bick, Stefan Bieschke, Joachim Ebert, and Walter Schmidt-Parzefall — Universität Hamburg, Institut für Experimentalphysik, Luruper Chaussee 149, 22761 Hamburg

The SHiP experiment (Search for Hidden Particles) requires a high intensity beam dump, which could be realized by a new facility at the Cern SPS accelerator. In total 2×10²⁰ protons of 400 GeV will hit the molybdenum-tungsten target and produce, amongst others, neutrinos of all flavors from decaying mesons. Therefore an additional neutrino subdetector, based on the high resolution emulsion cloud chamber technology of Opera, Chorus and Donut, will be placed upstream of SHiPs detector for the hidden sector. We expect a total of O(2M) ν_µ events, O(1M) ν_e events and O(5K) ν_τ events. A main goal is the measurement of ν_τ cross sections, where the present statistics of a few events will be increased by three orders of magnitude. The first observation of ν_τ is also within reach. Neutrino-nucleon deep-inelastic scattering is another challenging topic, especially the first measurement of structure functions F₄ and F₅.
