The Cusp Limit of Correlators and A New Graphical Bootstrap for Correlators/Amplitudes to Eleven Loops
Song He, Canxin Shi, Yichao Tang +1
We consider the universal behavior of half-BPS correlators in super-Yang-Mills in the cusp limit where two consecutive separations become lightl…
Scattering and bound observables for spinning particles in Kerr spacetime with generic spin orientations
Riccardo Gonzo, Canxin Shi
We derive the radial action of a spinning probe particle in Kerr spacetime from the worldline formalism in the first-order form, focusing on linear in spin effects. We then develop…
On universal splittings of tree-level particle and string scattering amplitudes
Qu Cao, Jin Dong, Song He +2
In this paper, we study the newly discovered universal splitting behavior for tree-level scattering amplitudes of particles and strings~\cite{Cao:2024gln}: when a set of Mandelstam…
A universal splitting of string and particle scattering amplitudes
Qu Cao, Jin Dong, Song He +1
We propose a new splitting behavior of tree-level string/particle amplitudes for scalars, gluons and gravitons. We identify certain subspaces in the space of Mandelstam variables,…
