SHiP: a new facility with a dedicated detector for studying tau neutrino properties

Abstract

SHiP (Search for Hidden Particles) is a new general purpose fixed target facility at the CERN SPS accelerator, with the aim of search for New Physics which has small coupling with standard particles by searching for long lived beyond standard model particles with masses below a few GeV/c2. The SHiP facility is a high intensity beam bump, the 400GeV proton beam extracted from the SPS will be dumped on a heavy target with the aim of integrating 2×1020 pot in 5 years. A dedicated detector, based on the OPERA-like ECC (Emulsion Cloud Chamber), will provide tau and anti-tau neutrino detection capability to study ντ and ν‾τ cross-sections with a statistics a few 100 times larger than the DONUT experiment. Moreover, the structure functions F4 and F5 which is only accessible by tau neutrino interactions can be measured first time. SHiP is the unique chance to study tau and anti tau neutrino properties.
