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…
