General relativity: from geometry to amplitudes

Workshop
27th June 2016 to 1st July 2016

Organisers: Professor Kirill K Krasnov (University of Nottingham), Professor Joel Fine (Université Libre de Bruxelles) and Dr Donal O'Connell (University of Edinburgh)

Workshop Theme

Gravity is a dynamical theory of metrics on space- time that follows from the standard Einstein-Hilbert action principle. However, there are indications from scattering amplitudes, string theory and twistor theory that this may not be the only or even the best way to understand the full structure of the theory. Important insights and simplifications arise by reformulating 4d gravity as a theory of connections on space-time rather than metrics. The manifolds of G2 holonomy suggest a link between 3d, 4d and 7d geometrical structures. One can alternatively formulate gravity and its amplitudes in (ambi-) twistor space leading to unexpected formulae and structures. The scattering amplitudes of general relativity appear to be a double copy of those in Yang-Mills theory. Furthermore, perturbative calculations of GR amplitudes do not use a space-time Lagrangian and indeed their connection to the standard Einstein-Hilbert action remains obscure. The aim of this workshop is to bring together experts working on these different aspects of gravity to obtain a more coherent understanding.
