Generalized Unitarity for Correlation Functions: 2 Different Approaches
Generalized unitarity is a very powerful method for computing amplitudes at loop level so it is natural to try to extend it to correlation functions. I will go through 2 different approaches to this: one is to apply the method directly to correlation functions, the other to establish something similar in real space. I will discuss the merits and drawbacks of both methods.
