Talk - "Identifying Regions for Asymptotic Expansions of Amplitudes"

• Yao Ma

The method of regions, a systematic approach to the asymptotic expansions of Feynman integrals, suggests that a Feynman integral can be reconstructed by summing over integrals expanded in certain regions. This technique not only facilitates the computation of Feynman integrals but also provides valuable insights for formulating an EFT, such as the Soft-Collinear Effective Theory (SCET). However, a fundamental question remains unanswered for most cases: how does one systematically determine the entire list of regions? This talk aims to address this question by drawing from some recent research works. In general, we classify the regions into two types, "facet regions" and "hidden regions". After a brief introduction, we will demonstrate the following results in detail. 1. For the "on-shell expansion" and the "soft expansion" of massless wide-angle scattering, an all-order result for facet regions is validated: only the hard mode, collinear modes, and ultrasoft mode are involved, with their interactions following certain rules. We have also found ample evidences that the same holds for hidden regions. 2. For the two-to-two forward scattering in the Regge limit, more complicated mode structures occur from three loops. In particular, hidden regions all feature the Glauber mode. Some important implications from these results will also be discussed in the talk.

Talk - "Causality bounds for gravitational EFTs "

• Scott Melville

When using higher-derivative interactions to parameterise the gravitational effects of new heavy degrees of freedom from the 'bottom-up', we typically treat the coefficients of these interactions as free parameters (to be fit to data). Recently, causality has been used to constrain the range of these coefficients in both the EFT and in the underlying UV completion. I will describe some of these causality bounds and how they might be used to improve searches for new physics using gravitational waves.

Talk - "From Black Hole Scattering to Gravitational Waveforms"

• Gustav Mogull

Driven by the use of quantum field theory methods, we now have a vastly improved understanding of the classical gravitational two-body problem in the post-Minkowskian (PM) fast-velocity, weak-field regime. After summarising this progress, including recent 5PM scattering results produced using the Worldline QFT (WQFT) formalism, I will explain how this data can be leveraged in the strong-field regime using effective-one-body (EOB) resummation. First I will discuss the SEOB-PM model, which describes large-angle scattering of spinning black holes. Then I will introduce SEOBNR-PM: the first complete inspiral-merger-ringdown waveform model for spinning black holes to incorporate PM scattering data.
