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…
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…
Cuts and Contours
Carolina Figueiredo, Marcos Skowronek
The traditional formulation of string amplitudes via worldsheet integrals provides a parametrization of the moduli space that fails to expose the complete singularity structure of…
Large deformations of Tr() and the world at infinity
Shruti Paranjape, Marcos Skowronek, Marcus Spradlin +1
The amplitudes of the non-linear sigma model can be obtained from those of Tr() theory by sending the kinematic (Mandelstam) variables to infinity in a certain direction. In t…
Surfaceology for Colored Yukawa Theory
Shounak De, Andrzej Pokraka, Marcos Skowronek +2
Arkani-Hamed and collaborators have recently shown that scattering amplitudes for colored theories can be expressed as integrals over combinatorial objects simply constructed from…
