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 $S O (1, 4)$ 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…
