DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/103/">
 Scalars to Pions and Gluons: New structure closer to the real world</a>\nb
 y Carolina Figueiredo (Princeton) as part of NHETC Seminar\n\n\nAbstract\n
 Scattering amplitudes for the simplest theory of colored scalars— Tr phi
 ^3 theory — have been understood as arising from a counting problem asso
 ciated with curves on a surface (arXiv:2309.15913v1). This formulation pro
 duces “stringy” integrals for the amplitudes\, built off of variables 
 defined on the surface\, from which the field theory limit as $\\alpha^\\p
 rime \\to 0$ can easily be extracted. In this talk\, we will extend this a
 pproach to theories closer to the real world — in particular the non-lin
 ear sigma model and Yang-Mills theory (arXiv:2401.00041v1). We will explai
 n 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 feature
 s of the amplitudes present in all these colored theories — ranging from
  hidden patterns of zeroes to unusual factorization properties away from s
 ingularities (arXiv:2312.16282v1).\n
