  1. 1. Keynote Talk - A Snapshot of Preheating: success, challenges and possibilities
    Dr Tom Giblin (Kenyon College)

  2. 2. Perturbative Reheating and Thermalization
    Dr Kyohei Mukaida (KEK)
    04/03/2025, 11:15

    In this talk, we will discuss in detail the process of reheating that is dominated by the perturbative decay of inflaton.
    Thought it appears to be merely a textbook exercise, we will see that the underlying physical processes are involved, which calls for e.g., the understanding of in-medium cascade of energetic particles.
    We will also discuss how this refined understanding affects the...

  3. 3. The exact WKB analysis as an analytic approach to preheating
    Dr Seishi Enomoto (Yokohama National University)
    04/03/2025, 13:15

    Preheating is a crucial phase in the early universe where non-perturbative particle production occurs due to the oscillating backgroud field. While numerical methods have been widely used to study preheating dynamics, analytic approaches remain essential for gaining deeper theoretical insights and generalizing results across different models. In this talk, I will present the exact WKB analysis...

  5. 9. Reheating after Inflation: Characteristics and Constraints
    Dr Pankaj Saha (KEK)
    04/03/2025, 15:00

    Reheating, the period following inflation, marks the transition where the inflaton decays, populating the early universe with matter and radiation.
    This phase remains relatively unexplored due to the absence of direct observational evidence and the complex, non-linear dynamics involved.
    This talk will examine the characteristics and constraints of the reheating phase.
    As reheating...
