Black hole entropy, curved space and monsters
Stephen D. H. Hsu and David Reeb
21 June 2007
Almost all of the entropy of a given black hole must result from a smaller black hole which has absorbed some additional mass.
It is also worth noting that a single s-wave mode with energy m = 1/R = 1/M has entropy O(1), so satisfies S = Mm. Thus, a black hole can move along the S = A curve by absorbing such modes. This is arguably the smallest amount of energy that can be absorbed by the hole, since otherwise the Compton wavelength of the mode is much larger than the horizon itself.

What is he saying?
How would the Compton wavelength fit in with the ultraviolet and an infrared cutoff, if the cut off is as a result of the minimum length and the resulting structure?
The smallest black hole has got to be bigger than the smallest wavelength that can exist.

The average size of instantons found in ref. 11 is ¯_ ≈ 0.36 fm and their average separation is ¯R = (N/V )−1 4 ≈ 0.89 fm. Similar results have been obtained by other lattice groups using various techniques. A decade earlier the basic characteristics of the instanton ensemble were obtained analytically from the Feynman variational principle 12,13 and expressed through the only dimensional parameter _ one has in QCD: ¯_ ≈ 0.48/_MS ≃ 0.35 fm, ¯R ≈ 1.35/_MS ≃ 0.95 fm, if one uses _MS = 280MeV as it follows from the DIS data.

Nuclear matter in the chiral quark soliton model with vector mesons
S.Nagai1, N.Sawado, and N.Shiiki1,
(Dated: March 22, 2007)
The idea of investigating dense nuclear matter in the topological soliton models has been developed over decades. It was first applied for the nuclear matter system with the skyrmion centered cubic (CC) crystal by Klebanov [1]. This configuration was studied further by W¨ust, Brown and Jackson to estimate the baryon density and discuss the phase transition between nuclear matter and quark matter [2]. Goldhabor and Manton found a new configuration, body-centered cubic (BCC) of half-skyrmions in a higher density regime [3]. The face centered cubic (FCC) and BCC lattice were studied by Castillejo et al. [4] and the phase transitions between those configurations were investigated by Kugler and Shtrikman [5]. Recently, the idea of using crystallized skyrmions to study nuclear matter was revived by Park, Min, Rho and Vento with the introduction of the Atiyah-Manton multi-soliton ansatz in a unit cell [6].
The chiral quark soliton model (CQSM) can be interpreted as the soliton bag model including not only valence quarks but also the vacuum sea quark polarization effects explicitly [16, 17, 18, 19]. The model provides correct observables of a nucleon such as mass, electromagnetic value, spin carried by quarks, parton distributions and octet, decuplet SU(3) baryon spectra [20, 21].

I have already figured out (my blog) the smallest black hole would consist of 6 instantons and each would be limited to moving to 3 position. The smallest black hole would consist of 24 units. (S=A/4). Also, the smallest black hole can only grow by absorbing even numbers of quantas of energy. Odd numbers and fractions are not permitted.
----------------
From the above information I would be tempted to say that we could observe mini black holes at CERN.
What is going on? Is the logic faulty? Is spinfoam doomed?
