Pair creation in weak gravity and gauge backgrounds: spinning fields and binary stars
S. A. Franchino-Viñas, N. Varacalli, O. Zanusso
We study pair creation for quantum fields of spin , , and in the presence of weak gravitational and gauge backgrounds. Using resummed heat-kernel techniques, we obtain…
Critical and multicritical Lee-Yang fixed points in the local potential approximation
Dario Benedetti, Fanny Eustachon, Omar Zanusso
The multicritical generalizations of the Lee-Yang universality class arise as renormalization-group fixed points of scalar field theories with complex interaction, $n\i…
Physical Running in Conformal Gravity and Higher Derivative Scalars
Diego Buccio, Luca Parente, Omar Zanusso
We compute the physical running of a general higher derivative scalar coupled to a nondynamical metric and of higher derivative Weyl invariant gravity with a dynamical metric in fo…
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…
Consequences of the gauging of Weyl symmetry and the two-dimensional conformal anomaly
Omar Zanusso
We discuss the generalization of the local renormalization group approach to theories in which Weyl symmetry is gauged. These theories naturally correspond to scale invariant - rat…
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-…
