Full S-matrices and Witten diagrams with (relative) L-infinity algebras
Luigi Alfonsi, Leron Borsten, Hyungrok Kim +2
The -algebra approach to scattering amplitudes elegantly describes the nontrivial part of the -matrix but fails to take into account the trivial part. We argue that th…
Gravity from AKSZ-Manin theories in two, three, and four dimensions
Leron Borsten, Dimitri Kanakaris, Hyungrok Kim
We show that various dynamical gauge theories in two, three and four dimensions, obtained as Manin deformations of topological Alexandrov-Kontsevich-Schwarz-Zaboronsky (AKSZ) theor…
Ambitwistor Yang-Mills Theory Revisited
Leron Borsten, Branislav Jurco, Hyungrok Kim +2
Inspired by the Movshev-Mason-Skinner Cauchy-Riemann (CR) ambitwistor approach, we provide a rigorous yet elementary construction of a twisted CR holomorphic Chern-Simons action on…
Three-dimensional Yang-Mills theory is three-dimensional gravity with background sources
Leron Borsten, Dimitri Kanakaris, Hyungrok Kim
Chern-Simons theory with certain gauge groups is known to be equivalent to a first-order formulation of three-dimensional Einstein gravity with a cosmological constant, where both…
Out-of-time-order asymptotic observables are quasi-isomorphic to time-ordered amplitudes
Leron Borsten, Simon Jonsson, Hyungrok Kim
Asymptotic observables in quantum field theory beyond the familiar -matrix have recently attracted much interest, for instance in the context of gravity waveforms. Such observab…
