Abstract:
The Standard Model leaves several fundamental questions unanswered, including the nature of dark matter, the origin of neutrino masses, and the matter-antimatter asymmetry of the Universe. SHiP (Search for Hidden Particles) is a new general-purpose experiment in preparation at CERN's SPS, designed to explore feebly interacting particles at the intensity frontier. A high-intensity 400 GeV proton beam will produce large samples of heavy-flavor hadrons and photons in a beam-dump target, providing sensitivity to long-lived particles in the MeV-GeV mass range. The experiment combines a decay spectrometer with a scattering and neutrino detector, enabling searches for heavy neutral leptons, dark photons, dark scalars, axion-like particles, and light dark matter, together with a rich neutrino program. This talk will present the SHiP physics case, experimental concept, expected sensitivity, and its role in the broader search for physics beyond the Standard Model.

Prof. Lesya Shchutska is a faculty member at EPFL (École Polytechnique Fédérale de Lausanne), where she leads research at the forefront of particle physics. Her work spans both the intensity and energy frontiers, with major contributions to the LHCb and CMS experiments at the LHC. She has made significant contributions to precision tests of the Standard Model, including studies of lepton flavor universality and rare decays, as well as searches for new physics such as heavy neutral leptons, dark photons, and other feebly interacting particles. She is actively involved in the SHiP (Search for Hidden Particles) experiment at CERN, contributing to its physics case and detector development. Her recent research also explores physics opportunities at future facilities, including the Forward Physics Facility and the FCC.
