2 A schematic model for QCD at finite temperature
The simplest version of a class of toy models for QCD is presented. It is a Lipkin-type model, for the quark-antiquark sector, and, for the gluon sector, gluon pairs with spin zero are treated as elementary bosons. The model restricts to mesons with spin zero and to few baryonic states. The corresponding energy spectrum is discussed. We show that ground state correlations are essential to descr...
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 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 and Density
A general introduction into the subject aimed at a general theoretical physics audience. We introduce the sign problem posed by finite density lattice QCD, and we discuss the main methods proposed to circumvent it, with emphasis on the imaginary chemical potential approach. The interrelation between Taylor expansion and analytic continuation from imaginary chemical potential is discussed in det...
