1-Loop Divergences of Quantum Gravity Using Conformal Parametrization
G. de Berredo-Peixoto, A. B. Penna-Firme, I. L. Shapiro
We calculate the one-loop divergences for quantum gravity with cosmological constant, using new parametrization of quantum metric. The conformal factor of the metric is treated as…

On the high derivative fermionic operator and trace anomaly
G. de Berredo-Peixoto, I. L. Shapiro
We construct a new example of the high derivative four-dimensional conformal operator. This operator acts on fermions, and its contribution to the trace anomaly has opposite sign,…
