Scattering Amplitudes and The Cotton Double Copy
William T. Emond, Nathan Moynihan
We construct classical curvature spinors in topologically massive gauge theory and topologically massive gravity, expressed in terms of massive three-particle amplitudes. We show t…
Massive Covariant Colour-Kinematics in 3D
Nathan Moynihan
We explore topologically massive gauge theories using the covariant colour kinematics duality recently introduced by Cheung and Mangan. We show that the massive bi-adjoint scalar f…
Amplitudes from Coulomb to Kerr-Taub-NUT
William T. Emond, Yu-tin Huang, Uri Kol +2
Electric-magnetic duality, the Newman-Janis shift, and the double copy all act by elementary operations on three-point amplitudes. At the same time, they generate a network of inte…
Scattering Amplitudes and the Double Copy in Topologically Massive Theories
Nathan Moynihan
Using the principles of the modern scattering amplitudes programme, we develop a formalism for constructing the amplitudes of three-dimensional topologically massive gauge theories…
On-Shell Perspectives on the Massless Limit of Massive Supergravity
Daniel J Burger, Nathan Moynihan, Jeff Murugan
Massive gravity exhibits a famous discontinuity in its 2-point linearized amplitude for t-channel scattering of gravitational sources, in the limit. In essence, the sourc…
On-Shell Electric-Magnetic Duality and the Dual Graviton
Nathan Moynihan, Jeff Murugan
Using on-shell amplitude methods, we explore 4-dimensional Electric-Magnetic duality and its double copy. We show explicitly that the on-shell scattering amplitudes know about `dua…
