ABSTRACT：We discuss how the primordial universe can be used to probe high energy physics. For this purpose, the following topics will be covered: (1) An overview of cosmologicalcorrelation functions (non-Gaussianities). (2) Using inflation as a collider to probe the particle physics Standard Model and Beyond Standard Model physics. (3) Distinguishing inflation and alternative-to-inflation models from the outcome of the cosmological collider. (4) Probing the quantum aspects of the primordial universe.
