String-Like Dual Models for Scalar Theories
Christian Baadsgaard, N. E. J. Bjerrum-Bohr, Jacob L. Bourjaily +1
We show that all tree-level amplitudes in scalar field theory can be represented as the limit of an -invariant, string-theory-like dual model integral. Thes…
New Representations of the Perturbative S-Matrix
Christian Baadsgaard, N. E. J. Bjerrum-Bohr, Jacob L. Bourjaily +3
We propose a new framework to represent the perturbative S-matrix which is well-defined for all quantum field theories of massless particles, constructed from tree-level amplitudes…
Integration Rules for Loop Scattering Equations
Christian Baadsgaard, N. E. J. Bjerrum-Bohr, Jacob L. Bourjaily +2
We formulate new integration rules for one-loop scattering equations analogous to those at tree-level, and test them in a number of non-trivial cases for amplitudes in scalar …
Scattering Equations and Feynman Diagrams
Christian Baadsgaard, N. E. J. Bjerrum-Bohr, Jacob L. Bourjaily +1
We show a direct matching between individual Feynman diagrams and integration measures in the scattering equation formalism of Cachazo, He and Yuan. The connection is most easily e…
Integration Rules for Scattering Equations
Christian Baadsgaard, N. E. J. Bjerrum-Bohr, Jacob L. Bourjaily +1
As described by Cachazo, He and Yuan, scattering amplitudes in many quantum field theories can be represented as integrals that are fully localized on solutions to the so-called sc…
