The Conformal Anomaly Action to Fourth Order (4T) in $d=4$ in Momentum Space

Claudio Corianò, Matteo Maria Maglio, Dimosthenis Theofilopoulos

We elaborate on the structure of the conformal anomaly effective action up to 4-th order, in an expansion in the gravitational fluctuations $(h)$ of the background metric, in the f…
