Cosmological QCD phase transition in steady non-equilibrium dissipative Hořava-Lifshitz early universe
arXiv:1405.5033 · doi:10.1016/j.aop.2014.04.012
Abstract
We study the phase transition from quark-gluon plasma to hadrons in the early universe in the context of non-equilibrium thermodynamics. According to the standard model of cosmology, a phase transition associated with chiral symmetry breaking after the electro-weak transition has occurred when the universe was about old. We focus attention on such a phase transition in the presence of a viscous relativistic cosmological background fluid in the framework of non-detailed balance Hořava-Lifshitz cosmology within an effective model of QCD. We consider a flat Friedmann-Robertson-Walker Universe filled with a non-causal and causal bulk viscous cosmological fluid respectively and investigate the effects of the running coupling constants of Hořava-Lifshitz gravity, , on the evolution of the physical quantities relevant to a description of the early universe, namely, the temperature , scale factor , deceleration parameter and dimensionless ratio of the bulk viscosity coefficient to entropy density . We assume that the bulk viscosity cosmological background fluid obeys the evolution equation of the steady truncated (Eckart) and full version of the Israel-Stewart fluid, respectively.
