We consider (effective) Quantum General Relativity coupled to the Standard Model (QGR-SM) and study the corresponding BRST double complex. This double complex is generated by infinitesimal diffeomorphisms and infinitesimal gauge transformations. To this end, we define the respective BRST differentials P and Q and their corresponding anti-BRST differentials P and Q . Then we show that all differentials mutually anticommute, which allows us to introduce the total BRST differential D := P + Q and the total… 

Transversality in the Coupling of Gravity to Gauge Theories

We consider (effective) Quantum General Relativity coupled to the Standard Model and study its transversality. To this end, we provide all propagator and three-valent vertex Feynman rules. Then we

Complexes of marked graphs in gauge theory

We review the gauge and ghost cyle graph complexes as defined by Kreimer, Sars and van Suijlekom in “Quantization of gauge fields, graph polynomials and graph homology” and compute their cohomology.

Lecture Notes on Chern-Simons Perturbation Theory

The goal of these lectures is to exhibit the framing anomaly in the Batalin-Vilkovisky formulation of perturbative Chern-Simons theory. Concretely, we show that the partition function fails to

Covariant operator formalism of gauge theories and quantum gravity

This book provides a thorough description of the manifestly covariant canonical formalism of the abelian and non-abelian gauge theories and quantum gravity. The emphasis is on its non-perturbative
