چکیده
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. This suggests a complex picture of QGP in the region 1 − 1.5Tc.

Study of spatial meson correlators at finite temperature in quenched anisotropic lattice QCD
We analyze the meson correlator in the spatial direction at finite temperature. To achieve fine resolution in the spatial direction, we use an anisotropic lattice with the standard Wilson plaquette gauge action and the O(a) improved Wilson quark action. Below and above Tc, properties of correlators are investigated by two methods: fits with ansatz for the spectral function, and direct reconstru...
متن کاملTemporal meson correlators at finite temperature on quenched anisotropic lattice ∗
We study charmonium correlators at finite temperature in quenched anisotropic lattice QCD. The smearing technique is applied to enhance the low energy part of the correlator. We use two analysis procedures: the maximum entropy method for extraction of the spectral function without assuming specific form, as an estimate of the shape of spectral function, and the χ fit assuming typical forms as q...
متن کاملS-Wave Quarkonia in Potential Models
For the last twenty years the melting of heavy quark bound states has been considered an unambiguous signal for deconfinement [1]. Understanding the modification of the properties of heavy quarkonia in a hot medium is therefore essential for understanding deconfinement. Phenomenological studies based on potential models have been recently accompanied by lattice QCD calculations. The temperature...
متن کاملRecent progress in lattice QCD at finite temperature
I review recent progress in finite temperature lattice calculations, including the study of the nature of the deconfinement transition in QCD, equation of state, screening of static quarks and meson spectral functions.
متن کاملOperator Product Expansion and Quark-Hadron Duality: Facts and Riddles
We review the status of the practical operator product expansion (OPE), when applied to twopoint correlators of QCD currents which interpolate to mesonic resonances, in view of the violations of local quark-hadron duality. Covered topics are: a mini-review of mesonic QCD sum rules in vacuum, at finite temperature, or at finite baryon density, a comparison of model calculations of current-curren...
