Aug 16 – 20, 2021
Europe/Copenhagen timezone

The week of August 16-20, 2021, the Niels Bohr International Academy and the Niels Bohr Institute in collaboration with Penn State will proudly host Amplitudes 2021, the 13th in a series of annual conferences presenting the latest developments in the study of scattering amplitudes in quantum field theories.

While the conference was originally planned to be in-person, out of caution it will now be entirely online. Talks will begin each day at 1:00 PM CEST. We are grateful to Penn State for assistance with presenting a high-quality Zoom-based conference experience.


The conference will be preceded by a school on scattering amplitudes aimed at PhD students, organized by the SAGEX network.
