Mass/electric versus NUT/magnetic charges: duality from scattering amplitudes in and for all bosonic spins
Ricardo Monteiro, Lecheng Ren, Daniel Siretanu
We revisit Kerr-NUT metrics and related spin- fields in , and study their associated scattering amplitudes. Starting in position space, we highlight the interpretation o…
Energy-Energy Correlators at Strong Coupling
Max Jackson, Lecheng Ren, Bo Wang +1
We study energy-energy correlators (EEC) in planar super Yang-Mills theory at strong 't Hooft coupling . We consider the EEC in states created by half-BPS opera…
A Graphical Coaction for FRW Integrals from Partial/Relative Twisted (Co)homology
Andrew J. McLeod, Andrzej Pokraka, Lecheng Ren
We construct a graphical coaction for Friedmann-Robertson-Walker (FRW) integrals at all loop orders in conformally-coupled scalar theories with non-conformal polynomial interaction…
Energy-Energy Correlator from the AdS Virasoro-Shapiro Amplitude
Lecheng Ren, Bo Wang, Congkao Wen
We establish a precise formula relating the world-sheet integral of the AdS Virasoro-Shapiro amplitude to the energy-energy correlator (EEC) in super Yang-Mills the…
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 relie…
A Graphical Coaction for FRW Wavefunction Coefficients
Andrew McLeod, Andrzej Pokraka, Lecheng Ren
We show that the wavefunction of the universe in theories of conformally coupled scalars in power-law Friedmann-Robertson-Walker (FRW) cosmologies satisfies a graphical coaction, b…
