Abstract

Quantum Dilaton Gravity in two Dimensions with Fermions

We consider Generalized Dilaton Gravity models (GDTs) in two dimensions coupled nonminimally to massive and selfinteracting Dirac fermions. In the first order formulation of the theory, the path integral over the geometric sector can be evaluated explicitly, thus giving an effective action that includes all matter backreactions to geometry. The procedure is background independent. The matter integration is then treated perturbatively. One loop effects can be integrated using the conformal and chiral anomalies, and amongst the 4-Fermion-Vertices one corresponding to a Virtual Black Hole is found.
