One-Loop Yang-Mills Integrands from Scattering Equations
We investigate in the context of the scattering equations, how one-loop
linear propagator integrands in gauge theories can be linked to integrands with
quadratic propagators using a double forward limit. We illustrate our procedure
through examples and demonstrate how the different parts of the derived
quadratic integrand are consistent with cut-integrands derived from
four-dimensional generalized unitarity. We also comment on applications and
discuss possible further generalizations.Comment: 20 pages, 6 figures, typos corrected, added clarifications and
