"Post-Inflation Reheating: Review and Open Questions"

Our understanding of the state of the universe between the end of inflation and big bang nucleosynthesis (BBN) is incomplete. Post-inflation reheating — the energy transfer between the inflaton and Standard Model fields (possibly through intermediaries), and their subsequent thermalization — can provide clues to how inflation fits in with known high-energy physics; it is also critical for relating inflationary predictions to high-precision measurements. This talk will review our current understanding of the nonperturbative, nonlinear dynamics at the end of inflation and describe some salient features of reheating in (semi-)realistic models of particle physics. It will also focus on open questions regarding how the universe ultimately reaches a state of thermal equilibrium at a high temperature prior to BBN, with a radiation-dominated equation of state.
