DESCRIPTION:Speakers: Carolina Figueiredo (Princeton University)\n\nScatte
ring amplitudes for the simplest theory of colored scalars — Tr phi^3 th
eory — have been understood as arising from a problem associated with cu
rves on a surface (arXiv:2309.15913v1). This formulation produces “strin
gy” integrals for the amplitudes\, built off of variables defined on the
surface\, from which the field theory limit as $\\alpha^\\prime \\to 0$ c
an easily be extracted. In this talk\, we will extend this approach to the
ories closer to the real world — in particular the non-linear sigma mode
l and Yang-Mills theory (arXiv:2401.05483v2\,arXiv:2401.00041v1). We will
explain how amplitudes in these theories are surprisingly obtained from th
ose of the Tr $\\phi^3$ theory by simple shifts of the kinematic data. W
e will also explain how these “stringy” formulations expose universal
features of the amplitudes present in all these colored theories — rangi
ng from hidden patterns of zeroes to unusual factorization properties away
from singularities (arXiv:2312.16282v1).\n\nhttps://indico.hiskp.uni-bonn
