QCD Phase Transition at high Temperature in Cosmology
نویسنده
چکیده
The cosmological QCD phase transition is studied in terms of the color confinement at finite temperature using the dual Higgs theory of QCD. The confinement force is largely reduced at high temperature, which leads to the swelling of hadrons. We derive analytical formulae for the surface tension and the boundary thickness of the mixed phase from the effective potential at Tc. We predict a large reduction of the glueball mass near Tc. We investigate also the process of the hadron-bubble formation in the early Universe.

I describe the construction of effective field theories for equilibrium high-temperature plasma of elementary particles. 1 Motivation High-temperature and dense matter of elementary particles appears in several areas of physics. The first and most familiar example is the Universe at the early stages of its expansion. The Big Bang theory (for reviews see, e.g. 1,2) states that the Universe was h...

High-temperature and dense matter of elementary particles appears in several areas of physics. The rst and most familiar example is the Universe at the early stages of its expansion. The Big Bang theory (for reviews see, e.g. ) states that the Universe was hot and dense in the past, with a temperature ranging from a few eV up to the Planck scale MPl 10 GeV. Another place, where matter exists in...
متن کاملTricritical point of lattice QCD with Wilson quarks at finite temperature and density
First principle study of QCD at finite temperature T and chemical potential μ is essential for understanding a wide range of phenomena from heavy-ion collisions to cosmology and neutron stars. However, in the presence of finite density, the critical behavior lattice gauge theory without species doubling, is unknown. At strong coupling, we examine the phase structure on the (μ, T ) plane, using ...

The effect of subcritical hadron bubbles on a first-order quark-hadron phase transition is studied. These subcritical hadron bubbles are created due to thermal fluctuations, and can introduce a finite amount of phase mixing (quark phase mixed with hadron phase) even at and above the critical temperature. For reasonable choices of surface tension and correlation length, as obtained from the latt...
متن کاملLattice QCD at High Temperature and Density
After a brief introduction into basic aspects of the formulation of lattice regularized QCD at finite temperature and density we discuss our current understanding of the QCD phase diagram at finite temperature. We present results from lattice calculations that emphasize the deconfining as well as chiral symmetry restoring features of the QCD transition, and discuss the thermodynamics of the hig...
