Anomaly and double copy in quantum self-dual Yang-Mills and gravity
Ricardo Monteiro, Ricardo Stark-Muchão, Sam Wikeley
Recent works have explored how scattering amplitudes in quantum self-dual Yang-Mills theory and self-dual gravity can be interpreted as resulting from an anomaly, as first proposed…
Superstring loop amplitudes from the field theory limit
Yvonne Geyer, Ricardo Monteiro, Ricardo Stark-Muchão
We propose a procedure to determine the moduli-space integrands of loop-level superstring amplitudes for massless external states in terms of the field theory limit. We focus on th…
Propagators, BCFW Recursion and New Scattering Equations at One Loop
Joseph A. Farrow, Yvonne Geyer, Arthur E. Lipstein +2
We investigate how loop-level propagators arise from tree level via a forward-limit procedure in two modern approaches to scattering amplitudes, namely the BCFW recursion relations…
Monopoles, shockwaves and the classical double copy
Nadia Bahjat-Abbas, Ricardo Stark-Muchão, Chris D. White
The classical double copy relates exact solutions in biadjoint scalar, gauge and gravity theories. Recently, nonperturbative solutions have been found in biadjoint theory, which ha…
Two-Loop Scattering Amplitudes: Double-Forward Limit and Colour-Kinematics Duality
Yvonne Geyer, Ricardo Monteiro, Ricardo Stark-Muchão
We propose new formulae for the two-loop n-point D-dimensional integrands of scattering amplitudes in Yang-Mills theory and gravity. The loop integrands are written as a double-for…
Biadjoint wires
Nadia Bahjat-Abbas, Ricardo Stark-Muchão, Chris D. White
Biadjoint scalar field theory has been the subject of much recent study, due to a number of applications in field and string theory. The catalogue of exact non-linear solutions of…
