de Sitter Wavefunction from Quadrangular Polylogarithms: Polygon Graphs
Livia Ferro, Tomasz Lukowski, Shruti Paranjape +5
We present an explicit formula for the -gon graph contribution to the integrand of the cosmological wavefunction for conformally coupled theory in de Sitter space. Our res…
Cluster Algebras, Cube Roots, and Energy Correlators in SYM
Dani Kaufman, Marcus Spradlin, Anastasia Volovich +1
We provide a cluster algebraic construction of the cube root symbol letters that appear at leading order in the near-collinear expansion of the four-point energy correlator in $\ma…
de Sitter Wavefunction from Quadrangular Polylogarithms: Chain Graphs
Livia Ferro, Tomasz Lukowski, Lecheng Ren +4
We present an explicit formula for the -site chain graph contribution to the cosmological wavefunction for conformally coupled theory in de Sitter space. Our result relies…
Landau Analysis of One-Cycle Negative Geometries
Shruti Paranjape, Marcos Skowronek, Marcus Spradlin +2
We use geometric Landau analysis to determine the singularity structure of four-point, one-cycle negative geometries in super-Yang-Mills theory, which represent cer…
Energy Correlators from Star Integrals via Mellin Space
Anastasia Volovich, Di Wu, Kai Yan
We explore the Mellin space representation for the collinear limit of -point energy correlators in super-Yang-Mills theory. We show that these correlators can be wr…
Cluster Bootstrap for Cosmological Correlators
Shruti Paranjape, Marcos Skowronek, Marcus Spradlin +2
We show that cosmological wavefunction coefficients associated with -site chain and loop graphs for a cubic scalar theory in de Sitter spacetime have symbol alphabets given by s…
