Quark number susceptibilities from lattice QCD
Results from our recent investigations of quark number susceptibilities in both quenched and 2-flavour QCD are presented as a function of valence quark mass and temperature. A strong reduction (∼40%) is seen in the strange quark susceptibility above Tc in both cases. A comparison of our isospin susceptibility results with the corresponding weak coupling expansion reveals once again the non-pert...
متن کاملQuark number susceptibilities, strangeness and dynamical confinement
We report first results on the strange quark number susceptibility, χs, over a large range of temperatures, mainly in the plasma phase of QCD. χs jumps across the phase transition temperature, Tc, and grows rapidly with temperature above but close to Tc. For all quark masses and susceptibilities in the entire temperature range studied, we found significant departures from ideal-gas values. We a...
متن کاملQuark number susceptibilities from HTL-resummed thermodynamics
We compute analytically the diagonal quark number susceptibilities for a quarkgluon plasma at finite temperature and zero chemical potential, and compare with recent lattice results. The calculation uses the approximately self-consistent resummation of hard thermal and dense loops that we have developed previously. For temperatures between 1.5 to 5Tc , our results follow the same trend as the l...
متن کاملQuark Number Susceptibilities & The Wróblewski Parameter
The Wróblewski parameter is a convenient indicator of strangeness production and can be employed to monitor a signal of quark-gluon plasma production : enhancement of strangeness production. It has been shown to be about a factor two higher in heavy ion collisions than in hadronic collisions. Using a method proposed by us earlier, we obtained lattice QCD results for the Wróblewski parameter fro...
متن کاملComparing different hard-thermal-loop approaches to quark number susceptibilities
We compare our previously proposed hard-thermal-loop (HTL) resummed calculation of quark number susceptibilities using a self-consistent two-loop approximation to the quark density with a recent calculation of the same quantity at the one-loop level in a variant of HTL-screened perturbation theory. Besides pointing out conceptual problems with the latter approach, we show that it severely over-...
