Summary

Lance Dixon, a leading expert in scattering amplitudes, presents a survey of opportunities for AI in theoretical particle physics. He begins by contrasting the reductionist approach of particle theory with emergent phenomena, and outlines the standard model’s successes and limitations. He identifies three areas where AI could assist: exploring the space of possible theories (e.g., S-matrix bootstrap), computing precise predictions for colliders (multi-loop amplitudes), and discovering new theoretical structures from ’theory data’. He details the computational challenges of multi-loop amplitude calculations, such as solving large systems of linear equations and performing loop integrations, and mentions efforts to use genetic algorithms and reinforcement learning to optimize these tasks. He then highlights the simplicity of amplitudes in special theories like planar N=4 SYM, where the amplituhedron provides a geometric reformulation. The main project he describes involves using small transformer models to predict properties of scattering amplitudes in planar N=4 SYM, where billions of terms of theory data can be phrased as language. The models can predict many properties when part of the answer is provided, and the next phase aims to predict unknown answers. He emphasizes the importance of finding symbolic or analytic understanding, not just numerical predictions.
