SHiP: an Experiment to Search for Hidden Particles
Nicola Serra (University Zurich)
Seminar room 3, 15:00
While the Standard Model has been very successful in describing most known microscopic physics phenomena, there are evidences for the existence of physics beyond the Standard Model: the existence of dark matter, the baryon-antibaryon asymmetry in the Universe and the non-vanishing neutrino masses. All these problems might be solved postulating the existence of Heavy Neutral Leptons (HNLs), right-handed partners of Standard Model neutrinos.
The SHiP experiment is a new beam dump experiment at SPS of CERN that has been designed and optimised to search for HNLs in the 100MeV- few GeV region. In addition, a number of alternative theories of physics beyond the Standard Model predict the existence of light very long lived neutral particles, which escape detection at general purpose detectors. All these particles can be searched for directly at the SHiP experiment, which will allow to improve previous constraints by several orders of magnitude.
