Abstract :
Naked singularities in the gravitational backgrounds dual to gauge theories can be hidden behind the black hole horizon. We present an exact black hole solution in the Klebanov–Tseytlin geometry [I.R. Klebanov, A.A. Tseytlin, hep-th/0002159]. Our solution realizes Maldacena dual of the finite temperature N=1 duality cascade of [I.R. Klebanov, M.J. Strassler, hep-th/0007191] above the temperature of the chiral symmetry breaking. We compare the Bekenstein–Hawking entropy of the black hole with the entropy of the SU(N+M)×SU(N) gauge theory.
