Title	Primordial non-Gaussianities as a particle collider
Abstract	The energy scale of inflation could be as high as $10^14$ GeV, hence it is a phenomenon at the highest energy scale we may explore. Primordial non-Gaussianities can then be thought of as a $10^14$ GeV collider (dubbed the cosmological collider), which may be used to probe new particles at the inflationary scale. In this talk I will review recent progress in such a cosmological collider program including our own works. In particular I will discuss how to read of the mass and spin of new particles at various scales from non-Gaussianities.
