FSI hadronic reinteractions model vs. data

• Caveat 1: Very dense hadronic medium scenarios should result in partonic scenarios by definition.

• Caveat 2: Really quantitative calculations non-existent (more realistic description of hadronic expanding medium needed).

• 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 (due to the assumed 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, ...
