TASI Lectures on Primordial Cosmology
Daniel Baumann
TL;DR
This paper provides an overview of primordial cosmology, focusing on observational tests of new physics beyond the Standard Model through effects on cosmic microwave background anisotropies and inflationary imprints.
Contribution
It offers a comprehensive review of how light and massive particles produced in the early universe can be detected via cosmological observations.
Findings
Light particles affect CMB anisotropies
Massive particles leave signatures in higher-order correlations
Observational tests can probe physics beyond the Standard Model
Abstract
These lectures cover aspects of primordial cosmology with a focus on observational tests of physics beyond the Standard Model. The presentation is divided into two parts: In Part I, we study the production of new light particles in the hot big bang and describe their effects on the anisotropies of the cosmic microwave background. In Part II, we investigate the possibility of very massive particles being created during inflation and determine their imprints in higher-order cosmological correlations.
