Gluon Scattering in Expanding de Sitter Universe
Audrey Lindsay, Tomasz R. Taylor
We construct an observer-centric S-matrix in the expanding Poincaré patch of four-dimensional de Sitter space. The asymptotic states are defined along the worldline of a comoving,…
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…
Symmetries of de Sitter Particles and Amplitudes
Audrey Lindsay, Tomasz R. Taylor
We discuss the symmetry aspects of quantum field theory in global four-dimensional de Sitter spacetime linked to isometries. For the unitary irreducible representations r…
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…
