Ja n 19 94 Seeing the QCD phase transition with phi mesons

چکیده
A double phi peak structure in the dilepton invariant mass spectrum from ultrarel-ativistic heavy ion collisions is proposed as a signal for the phase transition from the quark-gluon plasma to the hadronic matter. The low mass phi peak results from the decay of phi mesons with reduced in-medium mass during the transition. Furthermore, the measurement of the transverse momentum distribution of these low mass phi mesons offers a viable means for determining the temperature of the phase transition.

LBL-35724 Secondary phi meson peak as an indicator of QCD phase transition in ultrarelativistic heavy ion collisions
Secondary phi meson peak as an indicator of QCD phase transition in ultrarelativistic heavy ion collisions Abstract In a previous paper, we have shown that a double phi peak structure appears in the dilepton invariant mass spectrum if a first order QCD phase transition occurs in ultrarelativistic heavy ion collisions. Furthermore, the transition temperature can be determined from the transverse...
متن کاملEffective mass of phi mesons at finite temperature
The effective mass of phi meson at non-zero temperature is re-examined with an effective chiral Lagrangian. We find that the phi mass decreases with temperature but the effect is small compared to the result obtained from calculations using QCD sum rules. The leading contributions come from kaon loop corrections but vector meson contributions are also important as temperature increases. We disc...

متن کاملConformal Phase Transition and Fate of the Hidden Local Symmetry in Large Nf QCD
It is observed that the Hidden Local Symmetry (HLS) for the vector mesons in the ordinary QCD with smaller Nf plays the role of the “Higgsed magnetic gauge symmetry” for the Seiberg duality in the SUSY QCD. For large Nf where the conformal phase transition with chiral restoration and deconfinement is expected to take place, we find that the HLS model also exhibits the chiral restoration by the ...

We report on a study of the finite-temperature chiral transition on an Nt = 4 lattice for 2 + 1 flavors of Kogut-Susskind quarks. We find the point of physical quark masses to lie in the region of crossover, in agreement with results of previous studies. Results of a detailed examination of the m u,d = ms case indicate vanishing of the screening mass of σ meson at the end point of the first-ord...
