Primordial Non‐Gaussianities from Inflation Models

This is a pedagogical review on primordial non‐Gaussianities from inflation models. We introduce formalisms and techniques that are used to compute such quantities. We review different mechanisms which can generate observable large non‐Gaussianities during inflation, and distinctive signatures they leave on the non‐Gaussian profiles. They are potentially powerful probes to the dynamics of inflation. We also provide a nontechnical and qualitative summary of the main results and underlying physics.
