Spectral Suppression of Asymptotic States in Supersymmetric QFT on de Sitter Backgrounds
Stefano Bellucci, Stefania De Matteo
We investigate the fate of asymptotic particle states in supersymmetric quantum field theories on de Sitter backgrounds, distinguishing algebraic field content from localized LSZ-l…

A structural criterion for asymptotic states in Supersymmetry
Stefano Bellucci, Stefania De Matteo
The occurrence of a field in a quantum field theory does not by itself establish the existence of a corresponding asymptotic particle. We formulate a structural criterion separatin…

Exterior-Polynomial Classification of Gravitino Mass Bilinears and Their Superspace Projection in Four Dimensions
Stefano Bellucci, Stefania De Matteo
We distinguish two algebraic classification problems for a four-dimensional Majorana vector-spinor. In the full derivative-free Lorentz-covariant sector, direct contraction of the…
