High pT suppression explainable too due to hadronic final-state interactions (*) !?

• (*) “comovers”-like explanation (parentheses for the SPS J/Psi story “connaisseur”)

• Dense hadronic medium: <L/l> ~ 2-3

• 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 ...”).
