Finite -Temperature QCD on the Lattice
Recent developments in finite-temperature studies of lattice QCD are reviewed. Topics include (i) tests of improved actions for the pure gauge system, (ii) scaling study of the two-flavor chiral transition and restoration of UA(1) symmetry with the Kogut-Susskind quark action, (iii) present understanding of the finite-temperature phase structure for the Wilson quark action. New results for fini...
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...
متن کاملLattice 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 کاملMeson correlators in finite temperature lattice QCD QCD - TARO Collaboration :
We analyze temporal and spatial meson correlators in quenched lattice QCD at T ≥ 0. Below Tc we observe little change in the meson properties as compared with T = 0. Above Tc we observe new features: chiral symmetry restoration and signals of plasma formation, but also indication of persisting “mesonic” (metastable) states and different temporal and spatial “masses” in the mesonic channels. Thi...
