Workshop “Twistors and Higher Spins”
The advent of twistor theory has led to profound insights in many areas of physics, such as scattering amplitudes, self-dual gauge theories, or holography and its more recent version, celestial holography. The latter has particularly benefited from the twistor point of view on null infinity, which helped clarifying aspects of asymptotic symmetries in flat space. Twistor theory also provides a natural language for describing massless fields in d=4 spacetime dimensions of any spin, which simplifies significantly the fields equations governing higher spin fields. The self-dual, or chiral, sector of higher spin gravity in 4d, revealed to be tractable and well-defined, once more illustrating the efficiency of twistor-inspired methods. The aim of this workshop is to gather together experts on twistor theory and higher spin gravity, to discuss recent progress in these two areas, and foster new directions of research.
