One-loop effective actions and higher spins
L. Bonora, M. Cvitan, P. Dominis Prester +3
The idea we advocate in this paper is that the one-loop effective action of a free (massive) field theory coupled to external sources (via conserved currents) contains complete inf…
Massive fermion model in 3d and higher spin currents
L. Bonora, M. Cvitan, P. Dominis Prester +2
We analyze the 3d free massive fermion theory coupled to external sources. The presence of a mass explicitly breaks parity invariance. We calculate two- and three-point functions o…
Pure contact term correlators in CFT
Loriano Bonora, Bruno Lima de Souza
We discuss the case of correlators in CFT made of pure contact terms, without a corresponding bare part. We show two examples. The first is provided by the conformal limits of a fr…
Trace anomalies in chiral theories revisited
Loriano Bonora, Stefano Giaccari, Bruno Lima de Souza
Motivated by the search for possible CP violating terms in the trace of the energy-momentum tensor in theories coupled to gravity we revisit the problem of trace anomalies in chira…
