We investigate how loop-level propagators arise from tree level via a forward-limit procedure in two modern approaches to scattering amplitudes, namely the BCFW recursion relations and the scattering equations formalism. In the first part of the pape... Read More about Propagators, BCFW recursion and new scattering equations at one loop.
