Description

We investigate the collinear behavior of tree level amplitudes in several theories using their CHY (Cachazo-He-Yuan) representation. We obtain the leading and subleading orders of the adjacent collinear limit and ask the question whether universality is present and how Einstein-Yang-Mills amplitudes emerge by checking specific identities due to Stieberger and Taylor.
