Carrollian Amplitudes and Celestial Symmetries
Lionel Mason, Romain Ruzziconi, Akshay Yelleshpur Srikant
Carrollian holography aims to express gravity in four-dimensional asymptotically flat spacetime in terms of a dual three-dimensional Carrollian CFT living at null infinity. Carroll…
Supersymmetry and the Celestial Jacobi Identity
Adam Ball, Marcus Spradlin, Akshay Yelleshpur Srikant +1
In this paper we study the simplifying effects of supersymmetry on celestial OPEs at both tree and loop level. We find at tree level that theories with unbroken supersymmetry aroun…
Scalar-Graviton Amplitudes and Celestial Holography
Adam Ball, Shounak De, Akshay Yelleshpur Srikant +1
We compute scattering amplitudes involving one massive scalar and two, three, or four gravitons. We show that when the conformal dimension of the massive scalar is set to zero, the…
Landau Singularities of the 7-Point Ziggurat II
Luke Lippstreu, Marcus Spradlin, Akshay Yelleshpur Srikant +1
We solve the Landau equations to find the singularities of nine three-loop 7-point graphs that arise as relaxations of the graph studied in arXiv:2211.16425. Along the way we estab…
