Exploring the early universe with the three-point function

Jorge Noreña
Instituto de Física, Pontificia Universidad Católica de Valparaíso, Valparaı́so, Chile

We will argue that the three-point correlation function of primordial fluctuations contains information about the field spectrum during inflation. This is somewhat similar to what happens in particle physics with scattering cross-sections. We will talk about what different limits and configurations tell us about the theory, and comment on future directions of research. We will then give an overview of how this is constrained and what are the future prospects for observations.
