Celestial Twistor Amplitudes
Graham R. Brown, Joshua Gowdy, Bill Spence
We show how to formulate celestial twistor amplitudes in Yang-Mills (YM) and gravity. This is motivated by a refined holographic correspondence between the twistor transform and th…

Amplitudes, Hopf algebras and the colour-kinematics duality
Andreas Brandhuber, Graham R. Brown, Gang Chen +3
It was recently proposed that the kinematic algebra featuring in the colour-kinematics duality for scattering amplitudes in heavy-mass effective field theory (HEFT) and Yang-Mills…
