Full result for the QCD equation of state with 2+1 flavors

We present a full result for the 2+1 flavor QCD equation of state. All the systematics are controlled, the quark masses are set to their physical values, and the continuum extrapolation is carried out. This extends our previous studies [JHEP 0601:089 (2006); 1011:077 (2010)] to even finer lattices and now includes ensembles with Nt = 6, 8, 10, 12 up to Nt = 16. We use a Symanzik improved gauge ...

Analysis of the finite temperature transition for 3 flavor QCD using p4-improved staggered fermions

We present a calculation of the transition temperature for 3 flavor QCD using p4-improved staggered fermions with two different variants of fattened links. We examine various susceptibilities at two different values for the temporal extent Nt = 4 and Nt = 6 in the vicinity of the 3 flavor transition at vanishing chemical potential. For Nt = 4, we study bare quark masses in the range mqa = 0.005...

Equation of state for two - flavor QCD with an improved Wilson quark action at non - zero chemical potential

The QCD thermodynamics on the lattice provides fundamental theoretical grounds to analyze the various experimental data in relativistic heavy ion collisions. So far, most of the numerical simulations on the lattice have been performed by using the staggered-type fermion actions. Therefore it is important to carry out studies using different fermion formulations to test the uncertainties of the ...

Numerical Study of the Equation of State for Two Flavor Qcd at Non-zero Baryon Density

We discuss the equation of state (EoS) for two flavor QCD at non-zero temperature and density. Derivatives of lnZ with respect to quark chemical potential μq are calculated up to sixth order. From this Taylor series, the pressure, quark number density and associated susceptibilities are estimated as functions of temperature and μq . It is found that the fluctuations in the quark number density ...

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...
