    In this talk I will introduce a novel particle physics framework addressing multiple cosmological tensions, including discrepancies in the Hubble parameter, S8, and Lyman-\alpha forest data. This model, SIDR+z_t (Self-Interacting Dark Radiation with transition redshift), features an inelastic dark matter (IDM) scenario coupled with dark radiation under a dark gauge symmetry. The model...

  7. 47. Modern Computational Approaches to Early Universe Modeling
    Jong-Hyun Yoon
    20/02/2025, 17:20

    In physics, while analytical calculations remain appealing, there are situations where the use of computers becomes indispensable. A straightforward example is the three-body problem, where even the interactions of just three bodies are challenging to solve analytically. This necessity is similarly evident in studies of the early universe. Understanding the dynamics of the inflaton requires...

    Shuntaro AOKI

    The cosmological collider program, which aims to extract direct information about heavy particles during inflation via primordial non-Gaussianity, has attracted attention as it offers a window into high-energy physics beyond the reach of terrestrial experiments. However, analyses based on concrete particle physics models remain limited, and it is still unclear under what conditions a large...

  11. 36. UV Freeze-In Dark Matter in General Reheating Scenarios
    Dr Kuldeep Deka (New York University Abu Dhabi)

    The dynamics of cosmic reheating, that is, on how the energy stored in the inflaton is transferred to the standard model (SM) thermal bath, is largely unknown. In this work, we show that the phenomenology of the nonbaryonic dark matter (DM) ultraviolet freeze-in production strongly depends on the dynamics of the cosmic-reheating era. Using a general parametrization for the Hubble expansion...
