The Joy of the Double Copy - Part 1

This lecture is the first part of "The Joy of the Double Copy" series presented by Henrik Johansson from Uppsala University as part of the KITP Program "What is Particle Theory?" (#particles25). Explore the fascinating concept of the double copy in particle physics through this comprehensive 1 hour and 34 minute presentation from the Kavli Institute for Theoretical Physics. Discover how this field-spanning program aims to integrate new developments in formal, computational, and phenomenological theory to address central questions in particle physics while driving further theoretical progress. The lecture is designed to bring together diverse perspectives and methods that may lead to entirely new questions in particle theory research.
