SHiP - Search for Hidden Particles

초록

The SHiP (Search for Hidden Particles) is a newly-proposed experiment (P-350) at the CERN SPS to explore hidden particles with mass from sub-GeV up to O(10) GeV. This long detector with a total length of about 150 m is designed to search for very-weakly-interacting long-lived particles, such as heavy neutral leptons (HNL). These particles should be produced in a proton beam dump at 400 GeV and decay in a long, evacuated, decay volume, and the SHiP detector will perform full reconstruction and particle identification for the decay products. Moreover, the facility is suited to studying tau neutrinos by using an emulsion target. About 3500 tau neutrinos are expected for integrated 2 × 1020 protons on target. Especially, anti-tau neutrinos are expected to be observed for the first time in this experiment. Recently, a Korean group was formed and joined the SHiP Collaboration. In this paper, the physics and the design of the SHiP experiment, including our possible contributions, are presented. ? 2016, Korean Physical Society. All rights reserved.
