Ambitwistor Strings and the Scattering Equations on AdSS
Kai Roehrig, David Skinner
We construct an ambitwistor string that describes Type II supergravity on AdSS with pure NS flux. The background Einstein equations ensure that the model is anomaly f…
A Gluing Operator for the Ambitwistor String
Kai A. Roehrig, David Skinner
We present a new operator in the ambitwistor string which glues together correlators with fewer points or of lower genus. It underpins the recursive construction of tree-level CHY…
Chiral Splitting and Einstein--Yang--Mills Tree Amplitudes in 4d
Kai A. Roehrig
We present a world-sheet formula for all tree level scattering amplitudes, in all trace sectors, of four dimensional supersymmetric Einstein-Yang-Mills theory,…
On tree amplitudes of supersymmetric Einstein-Yang-Mills theory
Tim Adamo, Eduardo Casali, Kai A. Roehrig +1
We present a new formula for all single trace tree amplitudes in four dimensional super Yang-Mills coupled to Einstein supergravity. Like the Cachazo-He-Yuan formula, our expressio…
New Ambitwistor String Theories
Eduardo Casali, Yvonne Geyer, Lionel Mason +2
We describe new ambitwistor string theories that give rise to the recent amplitude formulae for Einstein-Yang-Mills, (Dirac)-Born-Infeld, Galileons and others introduced by Cachazo…
