Mixed-symmetry fields in de Sitter space: a group theoretical glance | | Thomas Basile

24 Dec 2016 | | Abstract: | We derive the characters of all unitary irreducible representations of the
(d+1)-dimensional de Sitter spacetime isometry algebra so(1, d+1), and propose
a dictionary between those representations and massive or (partially) massless
fields on de Sitter spacetime. We propose a way of taking the flat limit of
representations in (anti-) de Sitter spaces in terms of these characters, and
conjecture the spectrum resulting from taking the flat limit of mixed-symmetry
fields in de Sitter spacetime. We identify the equivalent of the scalar
singleton for the de Sitter (dS) spacetime. | | Source: | arXiv, 1612.8166 | | Services: | Forum | Review | PDF | Favorites | |
