Gravitational Effective Theories with Maximal Supersymmetry and a Peculiar Parity
Justin Berman, Simon Caron-Huot, Aditi V. Chandra +4
We study the space of four-dimensional ultraviolet completions for supergravity that are described at low energies by weakly-coupled effective field theories (EFTs)…
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…
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…
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…
Analytic Bounds on the Spectrum of Crossing Symmetric S-Matrices
Justin Berman
We derive two rigorous constraints on the spectrum of massive states in weakly coupled theories with massless scalars in the adjoint representation of a large- gauge group. Firs…
Corners and Islands in the S-matrix Bootstrap of the Open Superstring
Justin Berman, Henriette Elvang
We bootstrap the Veneziano superstring amplitude in 10 dimensions from the bottom-up. Starting with the most general maximally supersymmetric Yang-Mills EFT, we input information a…
Flattening of the EFT-Hedron: Supersymmetric Positivity Bounds and the Search for String Theory
Justin Berman, Henriette Elvang, Aidan Herderschee
We examine universal positivity constraints on scattering in 4d planar supersymmetric Yang-Mills theory with higher-derivative corrections. We present numerical evi…
Optimal Conditions for Environment-Assisted Quantum Transport on the Fully Connected Network
Sam Alterman, Justin Berman, Frederick W. Strauch
We present a theoretical analysis of the efficiency and rate of excitation transport on a network described by a complete graph in which every site is connected to every other. The…
Freeze-in Leptogenesis via Dark-Matter Oscillations
Justin Berman, Brian Shuve, David Tucker-Smith
We study the cosmology and phenomenology of freeze-in baryogenesis via dark-matter oscillations, taking the dark matter to couple to Standard Model leptons. We investigate viable m…
