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…
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…
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…
On Unitarity of the Hypergeometric Amplitude
Gareth Mansfield, Marcus Spradlin
The hypergeometric amplitude is a one-parameter deformation of the Veneziano amplitude for four-point tachyon scattering in bosonic string theory that is consistent with -matrix…
On Noncommutative Multi-solitons
Rajesh Gopakumar, Matthew Headrick, Marcus Spradlin
We find the moduli space of multi-solitons in noncommutative scalar field theories at large theta, in arbitrary dimension. The existence of a non-trivial moduli space at leading or…
