CFT Realizations and Celestial Representation Theory of the Algebra

Bin Zhu

We study CFT realizations and celestial representations of the algebra. Free scalar and Dirac theories yield the same one-particle light-ray action.…

Three-Gluon Scattering Amplitude in de Sitter Spacetime

Tomasz R. Taylor, Bin Zhu

We study three-gluon scattering amplitudes in global de Sitter spacetime, in the angular momentum basis of SO(1,4) symmetry representations. At the tree level, they are determined…

Scattering of Quantum Particles in Global de Sitter Spacetime II: Scalars in Deep Infrared

Tomasz R. Taylor, Bin Zhu

We apply the S-matrix formalism developed in Part I to the interacting scalar theory in four-dimensional de Sitter spacetime. The amplitudes are computed in the angular momentum ba…

Scattering of Quantum Particles in de Sitter Spacetime I: The Formalism

Tomasz R. Taylor, Bin Zhu

We develop a formalism for computing the scattering amplitudes in maximally symmetric de Sitter spacetime with compact spatial dimensions. We describe quantum states by using the r…

Differential Equations for Carrollian Amplitudes

Romain Ruzziconi, Stephan Stieberger, Tomasz R. Taylor +1

Differential equations are powerful tools in the study of correlation functions in conformal field theories (CFTs). Carrollian amplitudes behave as correlation functions of Carroll…

Carrollian Amplitudes from Strings

Stephan Stieberger, Tomasz R. Taylor, Bin Zhu

Carrollian holography is supposed to describe gravity in four-dimensional asymptotically flat space-time by the three-dimensional Carrollian CFT living at null infinity. We transfo…

w(1+infinity) Algebra with a Cosmological Constant and the Celestial Sphere

Tomasz R. Taylor, Bin Zhu

It is shown that in the presence of a nonvanishing cosmological constant, Strominger's infinite-dimensional algebra of soft graviton symmetries is modified…
