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…
Bound States in Perturbative Quantum Gravity with Hydrogen-like Degeneracy
Callum R. T. Jones, Shruti Paranjape, Marcos Skowronek
Recent results in the study of gravitational scattering amplitudes indicate that some highly-symmetric relativistic systems may exactly conserve a version of the Laplace-Runge-Lenz…
Multi-Loop Negative Geometries
Lance J. Dixon, Umut Oktem, Shruti Paranjape +3
Scattering amplitudes in planar supersymmetric Yang-Mills theory are dual to expectation values of null polygonal Wilson loops. The Amplituhedron provides a geometric…
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…
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…
Split-Helicity Tree Amplitudes and Flag Cluster Algebras
Shruti Paranjape, Marcus Spradlin, Anastasia Volovich +1
Recent work has uncovered a connection between the symbol letters of general massless scattering and (permutations of) cluster variables of partial flag varieties. In this paper we…
