Lattice QCD at finite temperature
In the last years, much effort has been paid to experimentally detect the quark-gluon plasma (QGP) in heavy-ion collisions. In these experiments, precise theoretical inputs about the nature of the transition and the equation of state (EOS) of QGP are indispensable to unambiguously identify the signal of QGP. Here, lattice QCD provides us with the most powerful method to compute thermodynamic pr...
متن کاملLattice QCD at finite temperature
In recent years considerable progress has been made in understanding QCD at finite temperature using lattice simulations. Calculations of bulk thermodynamic quantities have been done in the realistic case of 2+1 flavors with sufficiently small quark masses using different versions of improved staggered actions [ 1, 2, 3, 4, 5]. This reduces or can even eliminate the uncertainty of extrapolation...
متن کاملDeterminants in QCD at finite temperature
We compute the functional determinant for the fluctuations around the most general selfdual configuration with unit topological charge for 4D SU(2) Yang-Mills with one compactified direction. This configuration is called “instanton with non-trivial holonomy” or “Kraan-vanBaal-Lee-Lu caloron”. It is a generalization of the usual instantons for the case of non-zero temperature. We extend the earl...
متن کاملProgress in Lattice QCD at finite temperature
I review recent developements in lattice QCD at finite temperature, including the determination of the transition temperature Tc, equation of state and diffenet static screening lengths. The lattice data suggest that at temperatures above 1.5Tc the quark gluon plasma can be considered as gas consisting of quarks and gluons.
متن کاملOn Perturbative Qcd at Finite Temperature
There is a number of interesting scenarios which are described by quantum field theories at finite temperature (electroweak phase transition, heavy ion collisions, etc.) In this talk I will focus on the deconfinement phase transition of QCD: lattice simulations suggest that hadron matter undergoes a transition into a phase in which quarks are deconfined at a temperature of order 150 MeV. This n...
