Integrability and unitarity

Understand

We show how generalised unitarity can be used to determine the one-loop dilatation operator in N=4 super Yang-Mills.

• Our analysis focuses on two sectors, namely the bosonic SO(6) sector and the SU(2|3) sector.
• The calculation is performed on shell, with no off-shell information introduced at any stage.
• In this way, we establish a direct connection between scattering amplitudes and the dilatation operator of the N=4 theory.
