Chiral symmetry breaking in cascading gauge theory plasma

Abstract
N=1 supersymmetric SU(K+P)xSU(K) cascading gauge theory of Klebanov et.al [1,2] undergoes a first-order finite temperature confinement/deconfinement phase transition at T_c=0.6141111(3) Lambda, where Lambda 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_cSB =0.882503(0) T_c > T_u the deconfined phase of the cascading plasma is perturbatively unstable towards development of the chiral symmetry breaking condensates. We present evidence that the ground state of the cascading plasma for T<T_cSB can not be homogeneous and isotropic.
