χSB in cascading gauge theory plasma

N = 1 supersymmetric SU(K + P) x SU(K) cascading gauge theory of Klebanov et al. (Klebanov and Tseytlin (2000) Ill, Klebanov and Strassler (2000) [2]) undergoes a first-order finite temperature confinement/deconfinement phase transition at T-c = 0.6141111(3)A, where A is the strong coupling scale of the theory. The deconfined phase of the theory, with the unbroken chiral symmetry, extends down to T-u= 0.8749(0)T-C, where it becomes perturbatively unstable due to the condensation of the hydrodynamic (sound) modes. We show that at T-chi SB = 0.882503(0)T-c > T-u the deconfined phase of the cascading plasma is perturbatively unstable towards development of the chiral symmetry breaking (chi SB) condensates. We present evidence that the ground state of the cascading plasma for T < T-chi sB cannot be homogeneous and isotropic. (C) 2011 Elsevier B.V. All rights reserved.
