Particle Physics workshops

Bring together amplitude-bootstrap approaches to string theory in flat and curved backgrounds. Researchers will discuss how bootstrap constraints reveal the structure of string amplitudes and how these methods extend to cosmological observables and anti-de Sitter or de Sitter settings. The workshop connects communities studying the S-matrix, cosmological correlators and quantum gravity through presentations and scientific discussion. 30 November 2026 at 09:00 through 4 December at 17:00, Asia/Taipei (UTC+8). Public participant registration closes on 20 November 2026.

Explore path-integration techniques linking quantum mechanics, quantum field theory and gravity. Five themes connect worldline methods, strong external backgrounds, heat-kernel expansions and resurgence, on-shell quantities, and geometry in first quantisation. Discussion includes curved spaces, superspace and nontrivial topology, as well as representations of wavefunctions, scattering amplitudes and gravitational waveforms. Review lectures introduce challenges in each area, followed by invited and contributed talks, two poster sessions and extended collaborative discussions across research communities. 22 March 2027 at 17:00 through 2 April at 13:30, Europe/Paris. The local timezone changes from CET to CEST on 28 March. Expressions of interest close on 15 December 2026 and participation is confirmed by the end of the year. An Indico account is required. Capacity is 70. Estimated fees, including accommodation and meals, are EUR 1,330 for established or senior scientists and EUR 940 for early-career researchers, payable on arrival; limited travel support is being sought.
