Theoretical and Observational Bounds on Dynamical Chern-Simons Gravity as an Effective Field Theory

Alexander Cassem, Mark P. Hertzberg

Dynamical Chern-Simons gravity corrections must be extremely small on macroscopic scales to satisfy causality and unitarity.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

any dCS corrections to gravitational dynamics should likely be very small on macroscopic systems of observational interest, such as in late-time merging black holes.

C2weakest assumption

The choice of scale in the gravitational species bound and the validity of the specific N-fermion UV completion with (pseudo) Yukawa coupling are sufficient to constrain the effective theory.

C3one line summary

Dynamical Chern-Simons gravity is bounded by causality and perturbativity to produce only tiny corrections on macroscopic gravitational systems.
