Dlog Form of Super-Yang-Mills Loop Integrands


Abstract:


The scattering amplitudes of N=4 super-Yang-Mills theory exhibit many remarkable hidden symmetries and structures. After giving a brief introduction to N=4 super-Yang-Mills theory, I will describe a new form of hidden simplicity in the amplitudes, notably that the loop integrands can be expressed in dlog form. This form of the integrands arises geometrically from computing the scattering amplitudes using a holomorphic Wilson loop in twistor space.
