On the Perturbative Quantization of Einstein-Hilbert Gravity Embedded in a Higher Derivative Model II
Steffen Pottel, Klaus Sibold
In a previous paper we presented the renormalization of Einstein-Hilbert gravity under inclusion of higher derivative terms and proposed a projection down to the physical state spa…

On the Perturbative Quantization of Einstein-Hilbert Gravity Embedded in a Higher Derivative Model
Steffen Pottel, Klaus Sibold
In a perturbative approach Einstein-Hilbert gravity is quantized about a flat background. In order to render the model power counting renormalizable, higher order curvature terms a…

BPHZ Renormalization in Configuration Space for the -Model
Steffen Pottel
Recent developments for BPHZ renormalization performed in configuration space are reviewed and applied to the model of a scalar quantum field with quartic self-interaction. An exte…
