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 کاملUniversality and Scaling at the chiral transition in two-flavor QCD at finite temperature
The order of the phase transition in finite-temperature QCD with two degenerate light quarks is still an open problem and corresponds to the last question mark in the zero-density phase diagram of QCD. We argue that establishing the nature of the transition in this case is also a crucial test for numerical simulations of lattice QCD, allowing precise estimates of possible systematic errors rela...
متن کاملPerturbative Qcd at High Temperature
Recent developments of perturbation theory at finite temperature based on effective field theory methods are reviewed. These methods allow the contributions from the different scales to be separated and the perturbative series to be reorganized. The construction of the effective field theory is shown in detail for φ4 theory and QCD. It is applied to the evaluation of the free energy of QCD at o...
متن کاملQCD at high density/temperature
QCD now occupies an established position as the well-attested theory of strong-interaction physics. Other contributions to these proceedings (those of S. Frixione, L. Lellouch, and K. Long) survey the agreement between evidence from particle collider experiments and perturbative and lattice QCD calculations. However, there is more to QCD than collisions between pairs of particles. QCD should al...
متن کاملCharmonium at finite temperature
We study charmoinum correlators and spectral functions at finite temperature within the quenched approximation using isotropic lattices with lattice spacing a−1 = 4.86 GeV and 9.72 GeV. Although we observe some medium modifications of the ground state charmonium spectral function above deconfinement, we find that ground state charmonia (J/ψ and ηc) exist in the deconfined phase at least up to t...
