Entire Four-Graviton EFT from the Duality Between Color and Kinematics
John Joseph M. Carrasco, Sai Sasank Chava, Alex Edison +2
The Bern-Carrasco-Johansson (BCJ) double-copy construction reveals a fundamental structural connection between gauge and gravity theories. At its core, the BCJ double copy is direc…
Pinching rules in the chiral-splitting description of one-loop string amplitudes
Filippo Maria Balli, Alex Edison, Oliver Schlotterer
Loop amplitudes in string theories reduce to those of gauge theories and (super)gravity in their worldline description as the inverse string tension tends to zero. The appeara…
An exercise in Color-Dual Cut Tiling: Supergravity from Positivity
John Joseph M. Carrasco, Alex Edison, Nia Robles Del Pino +1
The BCJ duality between color and kinematics brings two advantages to calculating multi-loop scattering amplitudes. First the number of ordered cuts that need to be performed to fi…
Revealing the Landscape of Globally Color-Dual Multi-loop Integrands
Alex Edison, James Mangan, Nicolas H. Pavao
We report on progress in understanding how to construct color-dual multi-loop amplitudes. First we identify a cubic theory, semi-abelian Yang-Mills, that unifies many of the color-…
Perfecting one-loop BCJ numerators in SYM and supergravity
Alex Edison, Song He, Henrik Johansson +3
We take a major step towards computing -dimensional one-loop amplitudes in general gauge theories, compatible with the principles of unitarity and the color-kinematics duality.…
Color-kinematics dual representations of one-loop matrix elements in the open-superstring effective action
Alex Edison, Micah Tegevi
The -expansion of string theory provides a rich set of higher-dimension operators, indexed by values, which can be used to study color-kinematics duality and the double cop…
