In this talk, I will provide an overview of the scientific programme of the SHiP experiment from a theorist’s/phenomenologist’s perspective, focusing on scenarios beyond the Standard Model. I will begin with introducing the "lifetime frontier" of new physics - hypothetical particles with lifetimes that are too large for them to be searched for using traditional schemes at collider experiments. Then, I will describe the SHiP setup, as well as discuss its sensitivity to lifetime frontier particles with mass in the GeV range, considering different signatures. Finally, I will highlight the main complexities in robustly defining the parameter space of new particles to be probed by SHiP, which comes from large theoretical uncertainties and mismodelling in describing hadronic interactions.
