CONCLUSIONS
- Single-particle mT slopes give a freezeout temperature of about 140
meV, for AGS (at 15 A GeV) and CERN (160 A GeV) energies. This suggests
a picture of a heat bath that never exceeds a temperature equal to the
pion mass, and where additional energy just goes into more pions.

We can therefore boldly predict that at RHIC energies, the same method
will deliver the same temperature.
- FREEZER also gives the same temperature for AGS and CERN systems,
but it is markedly lower at 90 MeV. The origin of the discrepancy in not
understood. Will this method also give 90 MeV at RHIC? I'm betting yes.
