Analyticity of the Black Hole S-Matrix
Miguel Correia, Tushar Gopalka, Giulia Isabella +1
We establish the analytic structure of the S-matrix in the complex-frequency plane for classical wave scattering on a Schwarzschild background in four space-time dimensions. Our ar…
The planar two-loop four-point form factor in maximally supersymmetric Yang-Mills theory
Tushar Gopalka, Enrico Herrmann
We derive the four-dimensional integrand of the maximal-helicity-violating four-particle form factor for the chiral part of the stress-tensor supermultiplet in planar $\mathcal{N}=…
Classification of all 3 particle S-matrices quadratic in photons or gravitons
Soumangsu Chakraborty, Subham Dutta Chowdhury, Tushar Gopalka +3
We explicitly construct every kinematically allowed three particle graviton-graviton- and photon-photon- S-matrix in every dimension and for every choice of the little group…
Classifying and constraining local four photon and four graviton S-matrices
Subham Dutta Chowdhury, Abhijit Gadde, Tushar Gopalka +3
We study the space of all kinematically allowed four photon and four graviton S-matrices, polynomial in scattering momenta. We demonstrate that this space is the permutation invari…
