摘要：

The n-point correlation functions (n>2) of primordial fluctuations,

known as primordial non-Gaussianities, encode rich information about

the physical degrees of freedom and their interactions at inflation

scale, and can be viewed as signals from a cosmological collider with

huge energy. In this talk we introduce recent theoretical attempts to

extract new physics at the inflation scale from primordial

non-Gaussianities, including possible discovery channels, the

background signals from the standard model, and signals from new

physics such as heavy neutrinos.
