Charmonium in finite temperature lattice QCD
It is widely believed that the Quantum Choromodynamics (QCD) exhibits a phase transition at some temperature Tc, and quarks and gluons confined in the low temperature phase are liberated to form “quark gluon plasma”. At the beginning of 2000, CERN reported that the QGP state had been created in the heavy ion collision experiment[1]. In this experiment, the J/ψ suppression [2] is regarded as a k...
متن کاملCharmonium from Lattice QCD
Charmonium is an attractive system for the application of lattice QCD methods. While the sub-threshold spectrum has been considered in some detail in previous works, it is only very recently that excited and higherspin states and further properties such as radiative transitions and two-photon decays have come to be calculated. I report on this recent progress with reference to work done at Jeff...
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...
