Sphere path integrals for fermionic gauge fields
Chiara Baracco, Vasileios A. Letsios
We consider spin- complex, strictly massless fermionic gauge fields on the four-sphere, , which is the Euclidean continuation of de Sitter spacetime, dS$_4…
dS Metamorphosis
Dionysios Anninos, Chiara Baracco, Vasileios A. Letsios +1
We study the Euclidean path integral of higher spin gravity on . Based on a one-loop analysis, we are led to a gluing formula expressing the path integral in terms of an…
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…
Features of the Partition Function of a Universe
Dionysios Anninos, Chiara Baracco, Samuel Brian +1
We consider properties of the gravitational path integral, , of a four-dimensional gravitational effective field theory with at the quantum level. To leadi…
Remarks on 2D quantum cosmology
Dionysios Anninos, Chiara Baracco, Beatrix Mühlmann
We consider two-dimensional quantum gravity endowed with a positive cosmological constant and coupled to a conformal field theory of large and positive central charge. We study cos…
