Gravitational Effective Theories with Maximal Supersymmetry and a Peculiar Parity

Justin Berman, Simon Caron-Huot, Aditi V. Chandra +4

The paper investigates possible four‑dimensional UV completions of maximally supersymmetric (𝒩=8) supergravity by imposing tree‑level factorization and a special “peculiar parity”…

Efficient AI-Inspired Reduction of Feynman Integrals via Tube Seeding

Justin Berman, Francois Charton, Andres Luna +2

In this paper, we use machine learning to discover a new seeding strategy for integration-by-parts reduction of Feynman integrals, which is a frequent bottleneck in state-of-the-ar…

Positivity with Long-Range Interactions

B. Bellazzini, J. Berman, G. Isabella +3

We introduce infrared finite, analytic, crossing symmetric, Regge behaved, and Lorentz invariant amplitudes , labeled by the experimental energy resolut…

Splitting Regions and Shrinking Islands from Higher Point Constraints

Justin Berman, Henriette Elvang, Carolina Figueiredo

We study constraints from higher-point amplitudes on scattering in the context of effective field theory (EFT) using the perturbative numerical S-matrix bootstrap. Specif…

Analytic bootstrap bounds on masses and spins in gravitational and non-gravitational scalar theories

Justin Berman, Nicholas Geiser

We derive analytic constraints on the weakly-coupled spectrum of theories with a massless scalar under the standard assumptions of the S-matrix bootstrap program. These bootstrap b…

Bootstrapping Extremal Scalar Amplitudes With and Without Supersymmetry

Justin Berman, Henriette Elvang, Nicholas Geiser +1

We re-examine positivity bounds on the scattering of identical massless real scalars with a novel perspective on how these bounds can be used to constrain the spectrum of U…
