Descripción
Cluster algebras are beautiful mathematical objects that have proven tremendously successful in describing the singularities of scattering amplitudes in maximally supersymmetric Yang-Mills theory. In this talk, I provide evidence that they also underlie the analytic structure of known 2- and 3-loop contributions to Higgs+jet amplitudes in quantum chromodynamics (QCD). I further demonstrate that cluster algebras predict, for the first time, new singularities of 6-point 1-mass QCD processes such as W/Z boson production plus 3 jets. Their massless limit and 5-point 2-mass subkinematics also check highly nontrivially against known results in the literature.
