Scattering amplitudes for the simplest theory of colored scalars — Tr phi^3 theory — have been understood as arising from a problem associated with curves on a surface (arXiv:2309.15913v1). This formulation produces “stringy” integrals for the amplitudes, built off of variables defined on the surface, from which the field theory limit as $\alpha^\prime \to 0$ can easily be extracted. In this talk, we will extend this approach to theories closer to the real world — in particular the non-linear sigma model and Yang-Mills theory (arXiv:2401.05483v2,arXiv:2401.00041v1). We will explain how amplitudes in these theories are surprisingly obtained from those of the Tr $\phi^3$ theory by simple shifts of the kinematic data. We will also explain how these “stringy” formulations expose universal features of the amplitudes present in all these colored theories — ranging from hidden patterns of zeroes to unusual factorization properties away from singularities (arXiv:2312.16282v1).
