The Complete KLT-Map Between Gravity and Gauge Theories
Poul H. Damgaard, Rijun Huang, Thomas Sondergaard +1
We present the complete map of any pair of super Yang-Mills theories to supergravity theories as dictated by the KLT relations in four dimensions. Symmetries and the full set of as…
Feynman Rules for QCD in Space-Cone Gauge
Alexander Karlberg, Thomas Sondergaard
We present the Lagrangian and Feynman rules for QCD written in space-cone gauge and after eliminating unphysical degrees of freedom from the gluonic sector. The main goal is to cla…
Perturbative Gravity and Gauge Theory Relations -- A Review
Thomas Sondergaard
This review is dedicated to the amazing Kawai-Lewellen-Tye relations, connecting perturbative gravity and gauge theories at tree level. The main focus is on n-point derivations and…
Monodromy--like Relations for Finite Loop Amplitudes
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Henrik Johansson +1
We investigate the existence of relations for finite one-loop amplitudes in Yang-Mills theory. Using a diagrammatic formalism and a remarkable connection between tree and loop leve…
The Momentum Kernel of Gauge and Gravity Theories
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Thomas Sondergaard +1
We derive an explicit formula for factorizing an -point closed string amplitude into open string amplitudes. Our results are phrased in terms of a momentum kernel which in the l…
Proof of Gravity and Yang-Mills Amplitude Relations
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Bo Feng +1
Using BCFW on-shell recursion techniques, we prove a sequence of explicit n-point Kawai-Lewellen-Tye relations between gravity and Yang-Mills amplitudes at tree level.
New Identities among Gauge Theory Amplitudes
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Bo Feng +1
Color-ordered amplitudes in gauge theories satisfy non-linear identities involving amplitude products of different helicity configurations. We consider the origin of such identitie…
Gravity and Yang-Mills Amplitude Relations
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Bo Feng +1
Using only general features of the S-matrix and quantum field theory, we prove by induction the Kawai-Lewellen-Tye relations that link products of gauge theory amplitudes to gravit…
Monodromy and Jacobi-like Relations for Color-Ordered Amplitudes
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Thomas Sondergaard +1
We discuss monodromy relations between different color-ordered amplitudes in gauge theories. We show that Jacobi-like relations of Bern, Carrasco and Johansson can be introduced in…
New Relations for Gauge-Theory Amplitudes with Matter
Thomas Sondergaard
We extend a recently discovered set of relations for gauge-theory amplitudes to non-gluonic matter. For all MHV amplitudes we find that these can be made to hold for scalar/fermion…
