In recent years, an emerging common theme in quantum field theories and gravity is the exploration of Lorentzian methods and scattering data at asymptotic infinity to uncover fundamental properties of underlying theories. This approach manifests in diverse areas, including the study of scattering amplitudes and the S-matrix in gauge and gravity theories, the exploration of Lorentzian methods in conformal field theories, the use of asymptotic data for integrable systems, the analysis of gravitational waves from black hole mergers and energy flow from particle collisions. This program will bring together leading experts to discuss current progress and outstanding challenges in amplitudes, conformal bootstrap, energy correlators, gravitational waves, integrability, and S-matrix bootstrap. The goal is to foster discussion and catalyze new collaborations between these subfields, as well as to strengthen the dialogue between theory and experiment, paving the way for new developments.
The structure of the program is as follows:
Week 1 (Jan 5, 2026 -- Jan 9, 2026) : Dedicated lecture sessions on the aforementioned topics.
Week 2 (Jan 12, 2026 -- Jan 16, 2026): Research talks highlighting the latest advancements in these areas.
