Conformal gauge theory of vector-spinors and spin-3/2 particles
Dario Sauro
The unique off-shell fermionic gauge invariance of a vector-spinor field theory is found, and the invariant action is derived. The latter is Weyl invariant in any dimension in the…
Heat kernel of non-minimal second-order operators
Dario Sauro
We analyze the spectra of general non-minimal second-order operators. To do this, we derive the local part of the trace of the second Seeley-DeWitt heat kernel coefficient for such…
Hidden gauge invariances of torsion theories: closed algebras and absence of ghosts
Dario Sauro
We study the possible affine gauge transformations of the torsion tensor that make up Lie algebras. We find two such non-trivial structures, in which the gauge parameters are a …
Substructures of the Weyl group and their physical applications
Riccardo Martini, Gregorio Paci, Dario Sauro +2
We study substructures of the Weyl group of conformal transformations of the metric of (pseudo)Riemannian manifolds. These substructures are identified by differential constraints…
Composite higher derivative operators in dimensions and the spectrum of asymptotically safe gravity
Riccardo Martini, Dario Sauro, Omar Zanusso
We discuss the renormalization of Einstein-Hilbert's gravity in dimensions. We show that the application of the path-integral approach leads naturally to scheme- and gauge-…
Conformally covariant operators of mixed-symmetry tensors and MAGs
Gregorio Paci, Dario Sauro, Omar Zanusso
We compute conformally covariant actions and operators for tensors with mixed symmetries in arbitrary dimension . Our results complete the classification of conformal actions th…
Projective transformations in metric-affine and Weylian geometries
Dario Sauro, Riccardo Martini, Omar Zanusso
We discuss generalizations of the notions of projective transformations acting on affine model of Riemann-Cartan and Riemann-Cartan-Weyl gravity which preserve the projective struc…
The origin of Weyl gauging in metric-affine theories
Dario Sauro, Omar Zanusso
In the first part, we discuss the interplay between local scale invariance and metric-affine degrees of freedom from few distinct points of view. We argue, rather generally, that t…
On the Nelson-Seiberg theorem: generalizations and counter-examples
Antonio Amariti, Dario Sauro
In this note we elaborate on a recent counter-example to the Nelson-Seiberg theorem and to its generalizations. We provide sufficient conditions for the existence of such counter-e…
