A facility to Search for Hidden Particles (SHiP) at the CERN SPS

TL;DR

The proposed SHiP facility at CERN SPS aims to explore hidden particles and tau neutrinos, leveraging high-intensity beams to probe light exotic particles and potentially extend to dark matter and lepton flavor violation searches.

Contribution

Introduction of a new fixed target facility at CERN SPS designed to search for hidden particles and measure tau neutrinos, expanding the experimental reach beyond current capabilities.

Findings

Potential to probe light long-lived exotic particles below 10 GeV/c^2

Capability to extend to dark matter and lepton flavor violation searches

Utilization of high-intensity 400 GeV SPS beam for broad physics exploration

Abstract

A new general purpose fixed target facility is proposed at the CERN SPS accelerator which is aimed at exploring the domain of hidden particles and make measurements with tau neutrinos. Hidden particles are predicted by a large number of models beyond the Standard Model. The high intensity of the SPS 400~GeV beam allows probing a wide variety of models containing light long-lived exotic particles with masses below ${\cal O}$(10)~GeV/c$^2$, including very weakly interacting low-energy SUSY states. The experimental programme of the proposed facility is capable of being extended in the future, e.g. to include direct searches for Dark Matter and Lepton Flavour Violation.
