Chern-Simons Modified General Relativity: Conserved charges
Bayram Tekin
TL;DR
This paper develops a method to calculate conserved charges like mass and angular momentum in Chern-Simons modified General Relativity for asymptotically flat and AdS spacetimes, ensuring consistency with known limits.
Contribution
It introduces a new definition of conserved charges in Chern-Simons modified gravity that aligns with background symmetries and reduces to established formulas in special cases.
Findings
Conserved charges are explicitly constructed for asymptotically flat spacetimes.
The method applies to asymptotically AdS spacetimes as well.
The new definitions match known results in standard limits.
Abstract
We construct the conserved charges (mass and angular momentum) of the Chern-Simons modified General Relativity in asymptotically flat and Anti-de Sitter (AdS) spacetimes. Our definition is based on background Killing symmetries and reduces to the known expressions in the proper limits.
