Windings of twisted strings
Eduardo Casali, Piotr Tourkine
Twistor string models have been known for more than a decade now but have come back under the spotlight recently with the advent of the scattering equation formalism which has grea…
The complex null string, Galilean conformal algebra and scattering equations
Eduardo Casali, Yannick Herfray, Piotr Tourkine
The scattering equation formalism for scattering amplitudes, and its stringy incarnation, the ambitwistor string, remains a mysterious construction. In this paper, we pursue the st…
Amplitudes on plane waves from ambitwistor strings
Tim Adamo, Eduardo Casali, Lionel Mason +1
In marked contrast to conventional string theory, ambitwistor strings remain solvable worldsheet theories when coupled to curved background fields. We use this fact to consider the…
Scattering on plane waves and the double copy
Tim Adamo, Eduardo Casali, Lionel Mason +1
Perturbatively around flat space, the scattering amplitudes of gravity are related to those of Yang-Mills by colour-kinematic duality, under which gravitational amplitudes are obta…
