String-Generated Gravity Models

Boulware, David G., Deser, S.·1985·Physical Review Letters

Abstract

Expansion of supersymmetric string theory suggests that the leading quadratic curvature correction to the Einstein action is the Gauss-Bonnet invariant. We show that this model has both flat and anti-de Sitter space as solutions, but that the cosmological branch is unstable, because the graviton becomes a ghost there: The theory solves its own cosmological problem. The general static spherically symmetric solution is exhibited; it is asymptotically Schwarzschild. The sign of the Gauss-Bonnet coefficient determines whether there is a normal event horizon (for the string-generated sign) or a naked singularity. We discuss the effects of higher-curvature corrections and of an explicit cosmological term on stability.

TL;DR

The paper analyzes the effective gravity theory given by the Einstein action plus the leading quadratic curvature correction, the Gauss-Bonnet invariant, suggested by supersymmetric string expansion. It finds that the asymptotically flat branch is viable, while the anti-de Sitter cosmological branch is unstable because the graviton becomes a ghost.

Key findings

  • The Gauss-Bonnet combination is the only quadratic curvature term that avoids ghosts near flat space; the model has both flat and anti-de Sitter solutions, with positive Gauss-Bonnet coefficient corresponding to anti-de Sitter space.
  • The anti-de Sitter branch is intrinsically unstable: its graviton excitations are ghosts, and a positive-energy matter source leads to a negative-mass Schwarzschild–anti-de Sitter solution in which test particles are repelled.
  • The general static spherically symmetric solution is exhibited and is asymptotically Schwarzschild; the sign of the Gauss-Bonnet coefficient determines whether there is a normal event horizon (for the string-generated sign) or a naked singularity.
  • With an explicit cosmological term, the effective cosmological constant is shifted; the larger value is unstable and the lower one stable, and if \(4\Lambda\kappa^2 > n(n+1)\) the theory is undefined. For \(D=5\), horizon existence depends on whether \(2GM-\kappa\) is positive.

Methods

  • Theoretical analysis of the effective action in \(D=n+2\) dimensions, combining the Einstein term with the Gauss-Bonnet invariant, using form/vielbein methods and field equations.
  • The paper studies small perturbations about flat and anti-de Sitter backgrounds to identify ghost behavior, and derives general static spherically symmetric solutions in Schwarzschild gauge.
  • It also examines the effects of an explicit cosmological term and discusses higher-curvature corrections qualitatively; no empirical data or numerical simulations are used.

Limitations

  • The paper states that unresolved matters include the effect of compactification on the \(D>4\) constructions, the role of scalar and antisymmetric tensor fields and the Chern-Simons term, the canonical formulation, and a broader understanding of allowed classical geometries.
  • It states that higher-order questions are too early to speculate on, and that the scalar field neglected in the analysis will play a role in these questions.
  • It also notes that it has not considered whether semiclassical tunneling modifications occur through the existence of two branches of solutions. Evident from the text: the study is a classical effective-field-theory analysis, not a full string-theoretic treatment.

  • The negative-mass branch is called both de Sitter and anti-de Sitter

    Minor

    The paper consistently identifies the cosmological branch as anti-de Sitter, including when describing its negative-mass solution, but calls the same asymptotic solution Schwarzschild-de Sitter here.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-31, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-31 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
