Hadronic models: energy loss due to final-state hadron interactions

Dense hadronic medium (<L/l> ~ 2-3) seems to provide a flat suppression too ...
Main justification: fast parton hadronization time (i.e. inside expanding fireball)
[But, do thad estimates in pp (vacuum) apply to hadroniz. in (colored) medium ? ]
Description of scattering in the hadronic phase realistic enough ? (“... our calculations are at best semiquantitative ...”).
