Large extra dimension models predict TeV-scale black hole production at the LHC.
Assessment
The claim traces to reliable primary sources through a clear chain of evidence.
Large extra dimension models, introduced by Arkani-Hamed, Dimopoulos and Dvali in 1998, allow the fundamental scale of gravity to lie near a TeV rather than at the conventional Planck mass. A direct consequence, worked out in the collider literature from 2001 onward (notably by Dimopoulos and Landsberg and by Giddings and Thomas), is that if the fundamental scale is indeed near a TeV, proton collisions at the Large Hadron Collider would concentrate enough energy in a small enough region to form microscopic black holes, potentially at large rates. This conditional prediction is standard, uncontroversial physics within the model class and is routinely described in the literature as one of the least model-dependent signatures of TeV-scale gravity.
The claim concerns what the models predict, not whether nature realizes them. LHC searches have found no evidence of microscopic black holes, which constrains the models' parameter space but does not bear on the accuracy of the theoretical prediction itself.
Full reasoning — evidence and decisions behind this verdict
The claim is a statement about the content of a theoretical framework, and that content is thoroughly documented. Primary literature: Dimopoulos and Landsberg, "Black Holes at the LHC" (Phys. Rev. Lett. 87, 161602, 2001) computed production rates of roughly one black hole per second at the LHC if the quantum gravity scale is near a TeV; Giddings and Thomas (Phys. Rev. D 65, 056010, 2002) reached the same conclusion independently. A web check confirmed the framing: reviews describe copious micro black hole production as "one of the least modeldependent predictions of TeV-scale gravity", and the Beyond the Standard Model working-group report (hep-ph/0204031) repeats the one-per-second figure. The single source instance in the graph (Giddings and Mangano, arXiv:0806.3381, the LHC safety analysis) affirms the claim in its abstract, and no instance or credible source denies it.
The one load-bearing dependency is the presupposition that in large extra dimension models the fundamental gravity scale can be as low as about 1 TeV; this is the defining feature of the ADD construction and is uncontested as a model property. Given that, the prediction follows by standard hoop-conjecture reasoning about trans-Planckian collisions.
Care was taken over the word "predict": the prediction is conditional on the fundamental scale actually being near collider energies, and the models do not require that scale to be within LHC reach across their whole parameter space. Read charitably, as the literature itself states it, the claim is accurate. Credence 0.95 rather than higher only because "predict" compresses this conditionality. Null LHC search results (ATLAS and CMS limits on micro black holes) do not weigh against the claim, since it asserts a model prediction, not an observation.
