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…
