| Abstract: The entropy of supersymmetric black holes in string theory
compactifications can be related to that of a D- or M-brane system, which
in many cases can be further reduced to a two-dimensional conformal field
theory (2d CFT). For black holes in M-theory, this relation involves a
decoupling limit where the black hole mass diverges. We suggest that
moving away from this limit corresponds to a specific irrelevant
perturbation of the 2d CFT, namely the supersymmetric completion of the
Tar{T} deformation. We demonstrate that the black hole mass matches
precisely with the Tar{T} deformed energy levels, upon identifying the
Tar{T} deformation parameter with the inverse of the leading term of the
black hole mass. We discuss various implications of this novel realization
of the Tar{T} deformation, including a Hagedorn temperature for wrapped
M5-branes, and potential change of degeneracies in the deformed theory. |
