2027 Events

This workshop brings together researchers working on cosmological correlators and inflation, scattering amplitudes and gravitational-wave physics, and energy correlators at colliders. The goal is to explore the shared mathematical structures underlying these observables. The methodological focus is on unitarity, analyticity, bootstrap techniques and in-in methods, which increasingly connect these fields and support precision predictions. Motivated by upcoming cosmological surveys, next-generation gravitational-wave detectors and the high-luminosity LHC, the workshop aims to strengthen exchanges between communities that typically meet separately and build lasting scientific networks, in line with COST’s mission.
Target: WG1 (main), WG2. The workshop bridges WG1 (Gauge Theories) and WG2 (Gravity and Holography), connecting gauge-theory observables, gravitational-wave calculations and inflationary correlators.
Contact person: Lorenzo Di Pietro.

Symmetry and geometry have long been central organizing principles in fundamental physics. Recent years have witnessed substantial developments that have significantly broadened these notions and their applications at the interface of quantum field theory, gravity, geometry, and topology. The workshop will focus on three of these developments, namely 1) generalized and categorical symmetries, 2) non-Lorentzian symmetries and geometries and 3) higher structures and generalized geometry. The rapid development of generalized symmetries, non-Lorentzian geometry, and higher structures has created a need for dialogue between communities that often approach similar questions from different perspectives. The workshop aims to address this need by bringing together researchers from theoretical physics and mathematics working on these interconnected topics. Its primary goal is to foster interactions across disciplinary boundaries and to identify common challenges and open problems.
Target: WG1, WG2, WG3.
Contact person: Jan Rosseel.

The past decade has seen the convergence of quantum information theory, many-body chaos and gravity into a coherent and rapidly developing program aimed at unravelling the emergence of spacetime and the microscopic structure of black holes while also pushing the boundaries of our understanding of many-body dynamics. This conference is designed to catalyse this research, with a focus on young and emergent speakers.
Target: WG2.
Contact person: Stefano Baiguera.
