Title: Polytopes in particle physics, starting from associahedra
Abstract: The combinatorics of the associahedron provides a key to understanding the behavior of scattering amplitudes in theoretical particle physics. In this talk, we will explore a physics-inspired construction of a two-parameter family of polytopes -- and their curvy analogs -- which have prescribed sets of $\binom{n}{k}-n$ facet directions; associahedra provide the base case when $k=2$.
