The self-accelerating branch suffers from a negative energy ghost instability.
“However, as discussed in the introduction, SA branch suffers from a negative energy ghost instability.”
From Out of the White Hole: A Holographic Origin for the Big Bang (2014) · cites this paper as [8]
The Introduction and §3 describe a negative-kinetic-term radion and an associated negative-energy instability in the GRS model. They do not identify a self-accelerating (SA) branch or establish that this branch has the instability; that condition is unsupported by this source. (LLM, conf=0.84)
Experimental — accuracy not yet measuredSelf-accelerating DGP solutions suffer from ghosts and tachyons as well as some pathological singularities.
“However, it turned out that SA solutions suffer from ghosts and tachyons [8][9][10][11] as well as some pathological singularities [12].”
From Out of the White Hole: A Holographic Origin for the Big Bang (2014) · cites this paper as [8]
The Introduction and section 3 discuss a ghost radion and negative-energy effects in the GRS model, not self-accelerating DGP solutions. Searches for self-acceleration, DGP, tachyons, and pathological singularities found no passage addressing the attributed claim. (LLM, conf=0.78)

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.
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.
