Bulk locality for scalars and fermions with global symmetry

Subham Dutta Chowdhury, Kausik Ghosh

We count the number of independent solutions to crossing constraints of four point functions involving charged scalars and charged fermions in a CFT with large gap in the spectrum.…

Bounds on Regge growth of flat space scattering from bounds on chaos

Deeksha Chandorkar, Subham Dutta Chowdhury, Suman Kundu +1

We study four-point functions of scalars, conserved currents, and stress tensors in a conformal field theory, generated by a local contact term in the bulk dual description, in two…

Regge amplitudes in Generalized Fishnet and Chiral Fishnet Theories

Subham Dutta Chowdhury, Parthiv Haldar, Kallol Sen

We extend the analysis of \cite{Chowdhury:2019hns} to study the Regge trajectories of the Mellin amplitudes of the and magnon correlators of the generalized Fishnet theor…

Classification of four-point local gluon S-matrices

Subham Dutta Chowdhury, Abhijit Gadde

In this paper, we classify four-point local gluon S-matrices in arbitrary dimensions. This is along the same lines as \cite{Chowdhury:2019kaq} where four-point local photon S-matri…

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…
