Prospects of detecting the QCD critical point
We investigate the possibility to observe the QCD critical point in A + A collisions at the SPS. Guided by the QCD phase diagram expressed in experimentally accessible variables we suggest that the process C +C at 158 GeV /n freezes out very close to the critical point. We perform an analysis of the available preliminary experimental data for a variety of SPS processes. The basic tool in our ef...
متن کاملHydrodynamic Evolution Near QCD Critical Point
Hydrodynamics is usually adequate to describe the collective flow phenomena in macroscopic systems where thermodynamical relations are valid locally. Surprisingly enough, sometimes the hydrodynamical description is also useful as a model to describe the collective phenomena in microscopic and semi-microscopic systems. In fact, the collective flow behavior of hot, dense matter produced in relati...

متن کاملHow to Find the Qcd Critical Point
The event-by-event fluctuations in heavy ion collisions carry information about the thermodynamic properties of the hadronic system at the time of freeze-out. By studying these fluctuations as a function of varying control parameters, such as the collision energy, it is possible to learn much about the phase diagram of QCD. As a timely example, we stress the methods by which present experiments...
متن کاملCorrelation Probes of a QCD Critical Point
Critical opalescence is a characteristic experimental signature of a second order phase transition in solid state physics. A new, experimentally accessible measure of opacity and of attenuation length in heavy ion reactions is suggested, as a combination of HBT radii and nuclear modification factors. This opacity is maximal when √ sNN , the system size and centrality correspond to the critical ...
