Positive Geometry in Particle Physics and Cosmology

This is the kick-off workshop for the ERC-synergy project with the same title which starts in June 2024. Lectures and discussions will explore novel mathematical structures in fundamental physics, ranging from elementary particles to the Big Bang, and revealing hidden principles beyond quantum mechanics and spacetime. We will focus on positive geometries, such as amplituhedron, and their recent applications to scattering amplitudes and cosmology. The program of the week will begin with plenary presentations by international experts, and it will conclude with shorter research talks, informal discussions, and intense working groups. To foster interactions with Leipzig University, Daniel Baumann (University of Amsterdam) will give the Physics Colloquium on Tuesday, and Nima Arkani-Hamed (IAS Princeton) will give the Felix-Klein Colloquium on Wednesday.

Limited travel funding can be provided for early-career participants such as postdoctoral researchers and PhD students. Applicants are expected to submit a brief academic CV and a motivation letter. The application for funding is included in the registration form.

The deadline for registering will be December 15, 2023.
