From Trees to All Loops: The Combinatorial Geometry of Two-Site Cosmological Wavefunctions
Yanfeng Hang, Cong Shen
We prove, at arbitrary loop order and including arbitrary tadpole decorations, the shifted-tree decomposition of two-site cosmological wavefunction coefficients proposed in our pre…

Topological Equivalence Theorem and Double-Copy for Chern-Simons Scattering Amplitudes
Yan-Feng Hang, Hong-Jian He, Cong Shen
We study the mechanism of topological mass-generation for 3d Chern-Simons gauge theories and propose a brand-new Topological Equivalence Theorem to connect scattering amplitudes of…

Structure of Chern-Simons Scattering Amplitudes from Topological Equivalence Theorem and Double-Copy
Yan-Feng Hang, Hong-Jian He, Cong Shen
We study the mechanism of topological mass-generation for 3d Chern-Simons (CS) gauge theories, where the CS term can retain the gauge symmetry and make gauge boson topologically ma…
