The conformal anomaly action to fourth order (4T) in $$d=4$$ d = 4 in momentum space
Abstract 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 flat spacetime limit. For this purpose we discuss the renormalization of 4-point functions containing insertions o...
