  1. 51. 2-step FOEWPT in G2HDM
    TC Yuan (IOP, Academia Sinica)
    25/06/2025, 11:00
    Regular talk

    We investigate the possibility of a strong first-order electroweak phase transition (FOEWPT) during the early universe within the framework of the gauged two-Higgs doublet model (G2HDM) and explore its detectability through stochastic gravitational wave signals. The results indicate that forthcoming detectors such as BBO, LISA, DECIGO, TianQin and Taiji could potentially detect the...

  2. 38. Refining Gravitational Wave and Collider Physics Dialogue via Singlet Scalar Extension
    Dr Van Que Tran (NCTS, National Taiwan University)

    Regular talk

    Employing effective field theory techniques, we advance computations of thermal parameters that enter predictions for the gravitational wave spectra from first-order electroweak phase transitions. Working with the real-singlet-extended Standard Model, we utilize recent lattice simulations to confirm the existence of first-order phase transitions across the free parameter space. For the first...

  3. 46. Gravitational Dressing Operators and Radiative Observables from Binary Systems
    Karan Fernandes (NTNU)
    26/06/2025, 16:00
    Regular talk

    In recent years, classical limits of scattering amplitudes have emerged as a powerful tool for deriving state-of-the-art results for gravitational wave observables from interacting binary compact objects. In this talk, I will explore gravitational dressing operators from the worldline formalism and discuss their significance for late time radiative observables. We will first consider how...

  4. 32. The possibility of detecting dark matter with gravitational wave interferometers
    Hsiang-Chieh Hsu (Institute of Physics, Academia Sinica)
    26/06/2025, 16:30
    Regular talk

    We discuss the prospects for discovering macroscopic Dark Matter (DM) using large-scale ground-based gravitational wave (GW) detectors. Here, as an example, we consider a DM candidate with long-range Yukawa-like interactions in the kg- to tonne-scale mass range, where the analysis can potentially be further generalised for other DM models. The DM in this mass range will produce a signal that...
