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…
Unusual identities for QCD at tree-level
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Bo Feng +1
We discuss a set of recently discovered quadratic relations between gauge theory amplitudes. Such relations give additional structural simplifications for amplitudes in QCD. Remark…
