The Stringy S-matrix Bootstrap: Maximal Spin and Superpolynomial Softness
Kelian Häring, Alexander Zhiboedov
We explore the space of meromorphic amplitudes with extra constraints coming from the shape of the leading Regge trajectory. This information comes in two guises: it bounds the max…
Black hole bulk-cone singularities
Matthew Dodelson, Cristoforo Iossa, Robin Karlsson +2
Lorentzian correlators of local operators exhibit surprising singularities in theories with gravity duals. These are associated with null geodesics in an emergent bulk geometry. We…
Reconstructing -matrix Phases with Machine Learning
Aurélien Dersy, Matthew D. Schwartz, Alexander Zhiboedov
An important element of the -matrix bootstrap program is the relationship between the modulus of an -matrix element and its phase. Unitarity relates them by an integral equat…
Energy correlations in heavy states
D. Chicherin, G. P. Korchemsky, E. Sokatchev +1
We study energy correlations in states created by a heavy operator acting on the vacuum in a conformal field theory. We argue that the energy correlations in such states exhibit tw…
A thermal product formula
Matthew Dodelson, Cristoforo Iossa, Robin Karlsson +1
We show that holographic thermal two-sided two-point correlators take the form of a product over quasi-normal modes (QNMs). Due to this fact, the two-point function admits a natura…
Scattering amplitudes from dispersive iterations of unitarity
Piotr Tourkine, Alexander Zhiboedov
We present and numerically implement a computational method to construct relativistic scattering amplitudes that obey analyticity, crossing, elastic and inelastic unitarity in thre…
