QCD Meets Gravity Workshop 2017

QCD Meets Gravity Workshop 2017

December 11th-15th, 2017
UCLA Physics & Astronomy Department

This is the third in a series of meetings for researchers interested in the remarkable correspondence between Yang-Mills theory and gravity, known as the double-copy construction. An early manifestation of this is the KLT relations.

The BCJ double-copy construction has greatly simplified multiloop perturbative computations in gravity theories, leading to new insight into the ultraviolet properties of gravity theories. Currently there an intense global research activity to understand the origin of the relation as well as to apply it to more general classical solutions in General Relativity. This meeting will bring together experts in both QCD and gravity (including supersymmetric extensions), and focus on the development of common methodologies for handling both theories.

Organizers: Zvi Bern (UCLA), Clifford Chueng (Caltech), Donal O'Connell (Edinburgh), Radu Roiban (Penn State), Jaroslav Trnka (UC Davis), Henrik Johansson (Uppsala).
