Quark liberation and coalescence at CERN SPS

Quark liberation and coalescence at CERN SPS

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-)str...

Searching for Quark Matter at the CERN SPS

This article gives a brief overview of some recent advances in our understanding of the physics of dense strongly interacting matter, from measurements done at the CERN SPS. The presently available results are very interesting, and are likely to reflect the production of a new state of matter in central Pb-Pb collisions, at the highest SPS energies. However, important questions require further ...

Quark Gluon Plasma in A+a Collisions at Cern Sps

A GeV at CERN SPS

The measurement of multiple strange particles provides information on the hadronization features of strongly interacting matter produced in heavy ion collisions. If we assume that a deconfinement phase transition occurs in a heavy ion collision, we have to look for qualitative changes (onset phenomena) when varying external parameters like system size and energy density. Therefore we study the ...

Measurements at the CERN SPS

The current experimental situation concerning high pt observables at the CERN SPS is reviewed. Recent data from the NA45, NA49 and NA57 collaborations are discussed and compared to earlier measurements by WA98 and NA45 at the same center-of-mass energies, as well as to measurements at the higher energies by the RHIC experiments. The observables include new p+p, A+A spectra, nuclear modification...
