back to the indexTo test the model, Bernd ran his Hylander model, with parameters set to produce freezeout conditions corresponding to no flow and a high temperature. The resultant particle distributions were fed into Freezer, to see if it would reproduce these crazy conditions. Here is the result:
| name | description | expanding source model result | ``true'' value in HYLANDER |
|---|---|---|---|
| T | nuclear temperature | 167.6 +- 1.7 MeV | 160 MeV |
| v_t | transverse freezeout velocity | 0.00 +- .06 c | 0.01 c |
| R_t | transverse radius of source at beginning of freezeout | 7.49 +- .14 fm | 6.5 fm |
| tau_f | longitudinal freezeout proper time | 2.7 +- .2 fm/c | 1.4 fm/c |
| y_cm | the rapidity of the source's center relative to CM | 0.000 +- 0.004 | 0.0 |
| lambda_pi | fraction of pions produced incoherently | 1.045 +- 0.022 | 1.0 |
| mu_b/T | ratio of baryon chemical potential to temperature | 1.19 +- 0.05 | 1.52 |
| eta_0 | longitudinal spacetime rapidity of the right-hand end of the source in its own frame | 2.156 +- .013 | 1.47 |
| alpha_t | transverse freezeout coefficient related to the proper time width Delta-tau of freezeout | -1.00 +- .07 | ? |
As you can see, Freezer reoproduced the no-flow condition and the high temperature, sure a confidence-builing performance.
