Maksym Ovchynnikov (KIT): Search for new physics with the SHiP experiment

Sydney CPPC Seminar 13th June 2024

New physics may manifest itself via feebly interacting (equivalently, long-lived) particles in the GeV range. It would be quite challenging to search for them with main LHC experiments and later with FCC-ee. One of the flagships in exploring this parameter space is SHiP - a recently approved beam dump experiment that will operate at SPS@CERN. During the seminar, I will first discuss the long-lived particles in the GeV scale, describing complications with the description of their phenomenology. Then, I will briefly overview the status of current and future searches for them. Then, I will describe the SHiP's setup and proceed to its physics case, going from the exclusion sensitivity to discovery reach. In particular, I will demonstrate how SHiP will be able to establish the relation of the would-be-observed particles to the resolution of the BSM problems.
