Ladder Operators and Fermionic Tensor Fields on Maximally Symmetric Spaces
Facundo L. Cruz, Matias N. Sempé, Guillermo A. Silva
We construct first-order ladder operators for spin- Dirac fields and transverse, -traceless spin- Rarita--Schwinger fields on maximally symmetric space…
Fermionic fields of higher spin in de Sitter space
Dionysios Anninos, Chiara Baracco, Vasileios A. Letsios +1
We consider fermionic fields of higher spin on a four-dimensional de Sitter background. A particular emphasis is placed on the Rarita-Schwinger spin- case. Both massi…
Spinning fields on S and dS, UIRs and Ladder operators
Vasileios A. Letsios, Matías N. Sempé, Guillermo A. Silva
We construct, for spin tensor fields on S, a set of ladder operators that connect the distinct UIRs of SO. This is achieved by relying on the conformal Killing v…
Notes on Gauge Fields and Discrete Series representations in de Sitter spacetimes
Alan Rios Fukelman, Matías Sempé, Guillermo A. Silva
In this note we discuss features of the simplest spinning Discrete Series Unitary Irreducible Representations (UIR) of SO(1,4). These representations are known to be realised in th…
