Probing hidden sectors with the SHiP experiment at CERN — •James Webb for the SHiP-D collaboration — Albert-Ludwigs-Universität Freiburg, Physikalisches Institut, 79104 Freiburg, Germany
SHiP (Search for Hidden Particles) is a general purpose fixed target experiment. Approved in 2024 by the CERN research board, SHiP will be CERNs flagship experiment in the search for GeV-scale Feebly Interacting Particles (FIPs) and accelerator neutrino physics.
A 400 GeV/c proton beam extracted from the Super Proton Synchrotron (SPS) will be dumped on a heavy target, producing an expected 6× 1020 proton-target collisions over 15 years of operation. A dedicated detector, based on a long helium decay volume, surrounded by veto detectors, and then followed by a spectrometer and particle identification detectors, will allow for a variety of new physics models with light long-lived exotic particles to be probed in a near-zero background environment. This detector will increase the discovery sensitivity for many new physics models by orders of magnitude. A second detector dedicated to the study of neutrino cross-sections of all three flavours, will incorporate tracking and calorimetry detectors interwoven between five tonnes of tungsten and iron plates. The large neutrino flux produced during the beam dump coupled with the mass of the detector will yield a significant number of neutrino interactions that will become available for measurement.
In this talk a brief discussion on the physics potential and an overview of the detector layout, with an emphasis on the contributions from the German community, will be presented.
