Harmony of color and kinematics - from trees to loops

Johansson, H (Saclay)
Tuesday 03 April 2012, 16:00-17:30

Seminar Room 1, Newton Institute


Only a few years old, the idea that kinematic building blocks of scattering amplitudes have the same structure and properties as the Lie-algebra color factors - known as color-kinematics duality - has proven quite fruitful. Although the origins of the kinematic Lie-algebra structure remains unknown, it has improved our understanding of non-planar gauge theory and gravity. In this talk, I will review the status of color-kinematics duality at tree and loop level, illuminating the open problems as well as the techniques for calculating non-planar Yang-Mills and gravity loop amplitudes.
