Title: Enlarging the scope of the cosmological collider program
Abstract : Primordial non-Gaussianities can be thought of as a Hubble scale particle collider, so-called the cosmological collider program. In particular, their oscillating feature is a powerful tool to probe new particles around the Hubble scale just like the resonance peak of an ordinary particle collider. However, it is desirable to invent a new approach to probe particles heavier than the Hubble scale. In this talk, I will demonstrate that the sign of the inflation effective interactions can be used to probe spins of new particles heavier than the Hubble scale, enlarging the scope of the cosmological collider.
