From Scattering to Expansion

16 Oct 2019, 08:00 → 18 Oct 2019, 20:00 America/Chicago

F160 (Tech Institute, Northwestern University)

Daniel Baumann (University of Amsterdam), Daniel Green (UCSD), John Joseph Carrasco (Northwestern University & CEA-Saclay), Matthew Lewandowski (Northwestern University)

This meeting is to gather together established and new leaders in field theory and cosmology (broadly defined) to share recent insights and sharp questions, especially geared to engage early career researchers. This is intended to build upon conversations begun at a recent Simons Symposia: Amplitudes meet Cosmology [ https://www.simonsfoundation.org/event/amplitudes-meet-cosmology-2019/ ].

This workshop is by invitation only, please contact one of the organizers if you wish to attend.
