The complete action for de Sitter pure supergravity
Nicolas Boulanger, Vasileios A. Letsios, Sylvain Thomée
Supergravity theories in de Sitter spacetime are known to be very constrained, and rather unnatural within String/M Theory. We revisit the seminal paper by Pilch, van Nieuwenhuizen…
Unitary SUSY for the chiral graviton and chiral gravitino in de Sitter spacetime
Atsushi Higuchi, Vasileios A. Letsios
It is commonly believed that a unitary supersymmetric quantum field theory (QFT) involving graviton and gravitino fields on fixed 4-dimensional de Sitter spacetime () cannot…
Unitary Rigid Supersymmetry for the Chiral Graviton and Chiral Gravitino in de Sitter Spacetime
Atsushi Higuchi, Vasileios A. Letsios
It is commonly believed that a unitary supersymmetric quantum field theory (QFT) involving graviton and gravitino fields on fixed 4-dimensional de Sitter spacetime () canno…
Quite Discrete for a fermion
Vasileios A. Letsios, Ben Pethybridge, Alan Rios Fukelman
We study Discrete Series representations of with half-integer scaling dimension . At the classical level, we show that these UIRs are realised in the space of…
