Hadronic model vs. data

• Foreword: Very dense hadronic medium scenarios should have gone first through an (even) denser partonic phase.

• Magnitude of Au+Au suppression  dense hadronic medium:

  • High opacities: <n> = L/≈ 2
• pT dependence of Au+Au suppression  apparently described but with counter-intuitive arguments (in apparent contradiction to the assumed hadron formation time ansatz).
• Possible "control” calculations (not observed in data but expected in hadronic medium description): charm meson energy loss, suppressed near-side jet correlation, ...
