Modern approaches to scattering amplitudes
Recent years have seen tremendous advances in both our understanding of quantum field theory and in our ability to make predictions for experiment. The predicted probabilities for all the possible outcomes of any experiment are encoded by functions called scattering amplitudes.
The project is led by N. Emil J. Bjerrum-Bohr, Jacob Bourjaily and Poul Henrik Damgaard.

We acknowledge funding from the public foundations of Denmark (Danish National Research Foundation), from Eurepean Resarch Council and the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No. 764850 “SAGEX” ) as well as private Danish foundations (Carlsberg foundation, Lundbeck foundation, Villum Foundation).
Examples of the research being pioneered by researchers at the NBIA include:
- Exploring the connection between scattering amplitudes in
four-dimensional theories and Grassmannian geometry. - Developing powerful reformulations of perturbation theory; these include: extending on-shell recursion relations to (more) general theories, extending the scattering equation formalism to more theories and to higher orders, and enhancing unitarity-based methods to the integrand-level.
- The discovery of a new “Q-cut” representation of scattering amplitudes in perturbation theory that is free of the redundancies of the Feynman expansion.
- Improving our understanding of (and our ability to compute) the
transcendental functions relevant to scattering amplitudes in perturbation theory.
