TL;DR
This paper reviews the production of the first particles after cosmic inflation, focusing on reheating, baryogenesis, and leptogenesis, which are crucial for understanding matter-antimatter asymmetry and dark matter origins.
Contribution
It introduces the concept of first particle production between inflation and BBN, emphasizing the processes of reheating, electroweak baryogenesis, and leptogenesis.
Findings
Reheating converts inflation energy into particles.
Electroweak baryogenesis explains matter-antimatter asymmetry.
Leptogenesis contributes to dark matter formation.
Abstract
After cosmic inflation, the universe is cold and almost empty. Thus, the inflation field should decay to the particles for BBN through the so-called reheating process. Later, the matter-antimatter asymmetry and dark matter are produced. In this chapter, the ``first particle" production between the inflation phase and BBN phase is introduced. We focus on the reheating, electroweak baryogenesis, and leptogenesis.
