Matching with in long-range QFTs
Lorenzo Benfatto, Omar Zanusso
Irreversibility theorems -- such as the -theorem -- establish a hierarchy among fixed points of the renormalization group flow. The strongest thesis of this type of theorems wou…
Gradient properties of in
Lorenzo Benfatto, Omar Zanusso
The renormalization group flow of the multiscalar interacting theory in dimensions is known to have a gradient structure, in which suitable generalizations of the beta…
Ambient space and integration of the trace anomaly
Gregorio Paci, Omar Zanusso
We use the ambient space construction, in which spacetime is mapped into a special lightcone of a higher dimensional manifold, to derive the integrable terms of the trace anomaly i…
Weyl cohomology and the conformal anomaly in the presence of torsion
Gregorio Paci, Omar Zanusso
Using cohomological methods, we identify both trivial and nontrivial contributions to the conformal anomaly in the presence of vectorial torsion in dimensions. In both case…
