Holography for integrable field theories
Kevin Costello, Joaquin Liniado
We develop a holographic dual to the integrable field theories built from Chern-Simons theory. The dual theory is a topological string on a generalized Calabi-Yau manifold, wh…
Burns space and holography
Kevin Costello, Natalie M. Paquette, Atul Sharma
We elaborate on various aspects of our top-down celestial holographic duality wherein the semiclassical bulk spacetime is a 4d asymptotically flat, self-dual Kähler geometry known…
Bootstrapping two-loop QCD amplitudes
Kevin J. Costello
Form factors of self-dual gauge theory are equal to correlators of an (extended) celestial chiral algebra. This suggests that these form factors can be computed using the "bootstra…
Top-down holography in an asymptotically flat spacetime
Kevin Costello, Natalie M. Paquette, Atul Sharma
We propose a holographic duality for a four dimensional WZW model with target manifold , coupled to scalar-flat Kähler gravity on an asymptotically flat, four dimen…
On the associativity of one-loop corrections to the celestial OPE
Kevin Costello, Natalie M. Paquette
There has been recent interest in the question of whether QCD collinear singularities can be viewed as the OPE of a two-dimensional CFT. We analyze a version of this question for t…
Celestial holography meets twisted holography: 4d amplitudes from chiral correlators
Kevin Costello, Natalie M. Paquette
We propose a new program for computing a certain integrand of scattering amplitudes of four-dimensional gauge theories which we call the \textit{form factor integrand}, starting fr…
