We construct wavepackets on de Sitter spacetime, with masses consistently defined from the eigenvalues of an irreducible representation of a Casimir element in the universal enveloping algebra of the Lorentz algebra, and analyse their asymptotic behaviour. Furthermore, we show that, in the limit as...
