Does supersymmetry protect the relation R = 1 without requiring new fine-tuning?
Public summary of an internal test, not yet independently validated or published.
Question investigated
Does supersymmetry protect the relation R = 1 without requiring new fine-tuning?
Test conditions
Construct the minimal supersymmetric extension and distinguish protected contributions from Kähler corrections, supersymmetry breaking and gravitational effects. Derive the effective theory without subsequently retuning counterterms to impose R = 1.
Result
The minimal supersymmetric structure is insufficient to establish protection of R = 1. The Kähler terms, supersymmetry breaking and gravitational effects must be specified before the stability of the relation can be determined.
Physical interpretation
This test concerns the stability of the relation in the local effective theory. It does not determine the holographic origin of the scale or the fundamental theory.
