This afternoon workshop will continue the exchange activities between the “Cosmological Correlator”, which is part of the Cluster of Excellence ORIGINS, and the Max Planck–IAS–NTU Center for Particle Physics, Cosmology, and Geometry.
The event will bring together experts from leading institutes in Munich and Garching, including LMU and TUM, as well as the Max Planck Institutes for Physics (MPP), Astrophysics (MPA), and Extraterrestrial Physics (MPE).
In recent years, the particle physics and scattering amplitudes community has developed a variety of powerful new computational tools. These include innovative mathematical frameworks that enable more precise and efficient calculations. Although these methods were originally developed to address issues in collider physics, they have the potential to significantly impact cosmology, where similar challenges arise when studying the early and late Universe.
The Cosmological Connector aims to bring together researchers and create a common ground where ideas, methods, and expertise at the intersection of particle physics and cosmology can circulate freely. By building this bridge, we hope to open new pathways for solving long-standing questions about the fundamental laws of physics.
Following the success of the first edition, we are happy to host the second meeting, featuring a more interactive format focused on parallel discussion sessions.
Organisation
This event will centre around three broad thematic areas, with additional topics welcome at the beginning of the meeting. Participants will split into smaller groups for focused discussions aimed at identifying concrete problems, questions, and possible directions for collaboration.
At the end of the afternoon, we will reconvene for a joint brainstorming session to share insights and ideas across the different themes.
Discussion Themes (so far)
- Parity-violating trispectrum templates and corresponding UV theories
- Feynman integral toolkit for massive cosmological correlators
- Resummation methods in de Sitter
Everyone is encouraged to actively participate, bring ideas, and contribute to shaping the discussions, with the goal being to strengthen our collaborative network.
Registration closes on November 10, at 12:00 (noon).
