Quark liberation and coalescence at CERN SPS
نویسنده
چکیده
The mischievous linear coalescence approach to hadronization of quark matter is shown to violate strangeness conservation in strong interactions. The simplest correct quark counting is shown to coincide with the non-linear algebraic coalescence rehadronization model, ALCOR. The non-linearity of the ALCOR model is shown to cancel from its simple predictions for the relative yields of (multi-)strange baryons. We prove, model independently, that quark degrees of freedom are liberated before hadron formation in 158 AGeV central Pb + Pb collisions at CERN SPS. PACS number(s): 12.38.Mh, 13.87.Fh, 24.85.+p

The production of charm mesons from quark matter at CERN SPS and RHIC
We study the production of charm mesons and other charm baryons from quark matter at CERN SPS and RHIC energies. Using quark coalescence models as hadronization mechanism, we predict particle ratios, absolute yields and transverse momentum spectra. PACS numbers: 12.38.Mh, 13.87.Fh, 24.85.+p
متن کاملFaces of quark matter
Based on an analysis in the framework of a coalescence hadroniza-tion model (ALCOR) we conclude that in heavy ion collisions at CERN SPS and RHIC energies a new type of matter, the massive quark-antiquark matter is produced.
متن کاملEnergy dependence of transverse quark flow in heavy ion collisions
Energy dependence of quark transverse flow carries information about dynamical properties (equation of state, initial conditions) of deconfined matter produced in heavy ion collisions. We assume quark-antiquark matter formation in Pb+Pb collisions at CERN SPS and Au+Au collisions at RHIC energies and determine quark transverse flow at the critical temperature of the quark-hadron phase transitio...
متن کاملJ/ψ production from deconfined matter in relativistic heavy ion collisions
We study the production of the D and J/ψ mesons from deconfined quark matter at CERN SPS energy. Using the MICOR microscopical coalescence model we determine the transverse momentum spectra of these charm mesons. We predict the slopes of their transverse momentum spectra in Pb+Pb collision at 158 GeV/nucleon
متن کاملNew form of matter at CERN SPS: Quark Matter but not Quark Gluon Plasma
I argue that a new form of matter is indeed seen in Pb+Pb collisions at CERN SPS. This Quark Matter (QM) is different from the theoretically predicted Quark Gluon Plasma (QGP) because its effective degrees of freedom seem to be the massive (dressed) constituent quarks instead of almost massless quarks and gluons. The equation of state of QM is hard, the time of its rehadronization is short, whi...
