In the past decades, the Standard Model has been established to increasingly higher accuracy at experiments, which is a remarkable achievement for perturbation theory of both the strong and weak interactions. In contrast, tests for nonperturbative predictions of Standard Model physics are sorely lacking, even though nonperturbative phenomena lie at the heart of many expectations for SM and BSM physics. In particular, the role of EW sphalerons in baryogenesis, the role of QCD instantons in strong CP, and the fundamental mass gap problem of Yang-Mills theory are all commonly shared expectations about the behavior of SM physics beyond perturbation theory.

Fertile common ground has emerged for the mathematical structures that control perturbative calculations in different domains of fundamental physics – quantum field theory, general relativity, and their extension to string theory. This program brings together experts in these various domains of physics, as well as mathematicians with expertise in higher-genus surfaces and Calabi-Yau periods. Through an in-depth exchange among these communities, we aim to: · trigger technology transfer for advancing the precision frontier in perturbative quantum field theory and string theory, leading to insights that will impact both phenomenology, such as collider and gravitational-wave physics, and formal theory, such as string dualities and holography; · chart a course towards new understanding of the role of special functions in high energy physics, opening new avenues to reformulate quantum field theory and string theory to manifest the similarities of their mathematical structures.

The school focuses on quantum field theory, particle physics and (quantum) gravity, but other related areas of theoretical and mathematical physics (e.g. aspects of string theory, condensed matter physics, quantum information) also receive attention.

Our current best description of nature at the quantum scale is based on the Standard Model of particle physics (SM), while Einstein’s theory of relativity is based on a classical framework of space-time and describes cosmological scales. The fundamental incompatibility between the two descriptions is one of the big unsolved puzzles in physics. The existence of dark matter and dark energy and the apparent asymmetry between matter and antimatter are only two more of many more open questions that leave physicists puzzled. This seminar brings together experts from different fields of physics to discuss precision experiments to probe for New Physics that might hint towards solving these puzzles.

Topics include tests of Einstein’s theory of relativity using precision measurements in laboratory and large scale experiments, e.g. using spectroscopy, atom and nanoscopic particle interferometers, lunar laser ranging and gravitational wave detectors. A particular focus lies on the search for 5th forces extending to cosmological observations, isotope shift spectroscopy of neutral atoms and ions interpreted via King plot analysis, torsion balances and free-falling macroscopic bodies.

Effective field theory (EFT) is a powerful tool for describing the physics of systems at different energy scales. In the context of colliders and gravitational waves, EFTs together with multi-loop precision computation techniques play an essential role in creating precise theoretical predictions that can be compared with empirical data. Recently it has become evident that similar methods and computational tools can be successfully applied to the seemingly different fields of collider and gravitational wave physics. This workshop will bring together experts to discuss the latest developments in theory and phenomenology.

Resummation for the LHC: precision frontier, new structures, and jet processes; EFT tools for fixed order calculations; Factorization theorems at leading and subleading power; EFTs and expansions for gravitational wave astronomy; Scattering amplitudes in the classical regime; Multi-loop integrals for gravitational physics.
