  1. 1. Cosmological Dressing Rules
    Arthur Lipstein (University of Durham)
    12/02/2025, 15:30

    The basic observables in cosmology are known as in-in correlators. Recent calculations have revealed that in-in correlators in de Sitter space exhibit hidden simplicity stemming from a close relation to scattering amplitudes in flat space. In this talk, I will explain how to make this property manifest by dressing flat space Feynman diagrams with certain auxiliary propagators. Such dressing...

  2. 7. Lessons from the self-dual sector
    Silvia Nagy (University of Durham)
    12/02/2025, 16:45

    In this talk, I will explore how the self-dual sector of gravity and Yang-Mills theory provides a natural framework for formulating an elegant version of the double copy in curved spacetimes. Additionally, I will discuss how this perspective sheds light on the soft limits of these theories, offering a deeper understanding of their asymptotic behaviour.
