Minkowski and (A)dS ground states in general 2d dilaton gravity

TL;DR

This paper reorganizes the derivative expansion in 2d dilaton gravity to make the mass function integrable and classifies ground states as Minkowski, Rindler, or (A)dS based on model parameters.

Contribution

It introduces a new reorganization of the derivative expansion that ensures integrability of the mass function in 2d dilaton gravity models.

Findings

Identifies parameter conditions for Minkowski, Rindler, or (A)dS ground states.

Provides a framework to analyze ground states in general 2d dilaton gravity.

Demonstrates the applicability to a three-parameter family of models.

Abstract

We reorganize the derivative expansion of general (power-counting non-renormalizable) 2d dilaton gravity such that the mass function is integrable. As an example, we consider a three-parameter family of models and provide conditions on the parameters such that the ground state is either Minkowski, Rindler, or (A)dS.
