Thermal Flavor Production and Signatures of Deconfinement
نویسنده
چکیده
Using renormalization group methods we evaluate the thermal strangeness and charm chemical equilibrium relaxation times in the deconfined quark-gluon plasma. We present a reaction model and evaluate the total production rate of strangeness in fixed target Pb–Pb collisions at 10–300 A GeV. We discuss the relevance of our results to the diagnosis and understanding of the properties of the deconfined state.

Phenomenology of the three-flavor PNJL model and thermal strange quark production
We study the temperature dependence of the adjoint Polyakov loop and its implication for the momentum spectrum of gluons in the mean-field approximation. This allows us to calculate the contribution of the thermal (transverse) gluons to the thermodynamic pressure. As an application, we evaluate the rates for the strange quark pair-production processes q ¯ q → s¯ s and gg → s¯ s as functions of ...
متن کاملDeconfinement and Quarkonium Suppression
Modifications in the production pattern of heavy quark bound states have long been considered to provide sensitive signatures for the thermal properties of dense matter created in heavy ion collisions. The original concept of Matsui and Satz for quarkonium suppression as signature for deconfinement in heavy ion collisions has been challenged recently through lattice studies of spectral function...
متن کاملAspects of thermal strange quark production: the deconfinement and chiral phase transitions
We study the gluonic sector of the three-flavor PNJL model by obtaining the adjoint Polyakov loop and the gluon distribution function in the mean-field approximation. Besides, we explore the thermal strange quark pair-production processes, qq̄ → ss̄ and gg → ss̄, with the aid of the threeflavor PNJL model. The results help us identify the temperature where the gluonic contribution to the productio...
متن کاملThe Deconfinement Phase Transition in the Interior of Neutron Stars
The deconfinement phase transition which happens in the interior of neutron stars are investigated. Coupled with the spin evolution of the stars, the effect of entropy production and deconfinement heat generation during the deconfinement phase transition in the mixed phase of the neutron stars are discussed. The entropy production of deconfinement phase transition can be act as a signature of p...
متن کاملQuark Confinement and Deconfinement Transition in Large Flavor QCD
We give a new criterion of quark confinement/deconfinement by deriving a low-energy effective theory of QCD. The effective theory can explain Abelian dominance in low-energy physics of QCD, especially, quark confinement. Finally, we apply the above criterion to the large flavor QCD and discuss its phase structure. The result suggests the existence of conformal phase.
