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…
-Dimensional Modular Assembly of Higher-Derivative Four-Point Contact Amplitudes Involving Fermions
John Joseph M. Carrasco, Sai Sasank Chava, Alex Edison +1
We present a novel robust framework for systematically constructing -dimensional four-point higher-derivative contact amplitudes. Our modular block ("LEGO"-like) approach builds…
The double copy effective action: a quantum (chromodynamics) approach to space-time
John Joseph M. Carrasco, Suna Zekioglu
Conventional Lagrangian formulations of gauge and gravity theories emphasize compactness and off-shell symmetry. This often obscures the structure of on-shell physical observables.…
The Double-Copy Root of Hawking Thermality
John Joseph M. Carrasco, Yaxi Chen
The Hawking radiation spectrum from a collapsing null shell can be derived via the double copy of a simpler gauge theory calculation. Analyzing the non-abelian Yang-Mills root of t…
Nonperturbative double copy: worldline instantons, color thermality, and backreaction
John Joseph M. Carrasco, Yaxi Chen, Nicolas H. Pavao +1
We present a first-principles, non-perturbative worldline instanton analysis of vacuum decay in the non-abelian Yang-Mills root of a Schwarzschild background. We recover the gauge…
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…
