Cosmic inflation as a very high energy particle detector

Toshifumi Noumi

Kobe University, Japan

The energy scale of cosmic inflation could be as high as $10^{14}$ GeV, hence it is the highest energy scale we may explore. It is therefore interesting to explore a possibility to use inflation as a probe of new particles predicted by high energy theories (ex. supergravity, GUT, extra dimension). Such an idea is dubbed "cosmological collider physics." In this presentation, I will discuss how to use primordial non-Gaussianities to detect new particles by analogy with particle colliders.
