Lessons from PHOBOS
In June 2005 the PHOBOS Collaboration completed data taking at RHIC. In five years of operation PHOBOS recorded information for Au+Au at √sNN = 19.6, 62.4, 130, and 200 GeV, Cu+Cu at 22.4, 62.4 and 200 GeV, d+Au at 201 GeV, and p+p at 200 and 410 GeV, altogether more than one billion collisions....

| description | In June 2005 the PHOBOS Collaboration completed data taking at RHIC. In five years of operation
PHOBOS recorded information for Au+Au at
√sNN = 19.6, 62.4, 130, and 200 GeV,
Cu+Cu at 22.4, 62.4 and 200 GeV, d+Au at 201 GeV, and p+p at 200 and 410 GeV, altogether
more than one billion collisions. Using these data we have studied the energy and centrality dependence
of the global properties of charged particle production over essentially the full 4π solid
angle and (for pions near mid rapidity) charged particle spectra down to transverse momenta
below 30 MeV/c. We have also studied correlations of particles separated in pseudorapidity by
up to 6 units. We find that the global properties of heavy ion collisions can be described in terms
of a small number of simple dependencies on energy and centrality, and that there are strong
correlations between the produced particles. To date no single model has been proposed which
describes this rich phenomenology. In this talk I summarize what the data is explicitly telling us. |
