Basics of Color-Kinematics Duality and Double Copy - Class 1

Learn the fundamental principles of color-kinematics duality and the double copy construction in theoretical physics through this comprehensive lecture from the QCD meets Gravity School. Explore how gauge theory amplitudes can be reorganized to manifest a duality between color and kinematic structures, and discover how this duality enables the construction of gravity amplitudes from gauge theory building blocks through the double copy procedure. Delve into the mathematical foundations that connect quantum chromodynamics (QCD) with gravitational theories, examining the deep structural relationships between these seemingly different physical frameworks. Master the basic techniques and concepts that have revolutionized our understanding of scattering amplitudes in both gauge theories and gravity, providing powerful computational tools for high-energy physics calculations. Gain insights into this cutting-edge research area that bridges quantum field theory and general relativity, presented by Henrik Johansson from Uppsala University as part of the intensive physics school program.
