Auxiliary-Field Formalism for Higher-Derivative Boundary CFTs
Gregorio Paci, Sergey N. Solodukhin
We study the conformal field theory defined by the fourth-order operator on four-dimensional manifolds with boundaries, reformulating it through an auxiliary field so that the dyna…
Radiative corrections to the and invariants from torsion fluctuations on maximally symmetric spaces
Riccardo Martini, Gregorio Paci, Dario Sauro
We derive the runnings of the and operators that stem from integrating out quantum torsion fluctuations on a maximally symmetric Euclidean background, while treating the…
Euclidean actions and static black hole entropy in teleparallel theories
Iberê Kuntz, Gregorio Paci, Omar Zanusso
It is well-known that the results by Bekenstein, Gibbons and Hawking on the thermodynamics of black holes can be reproduced quite simply in the Euclidean path integral approach to…
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…
