Jetquenching in medium discovered@ RHIC but: Open Questions..

• How much of jet quenching due to JET->Hadron coll?

• Measure leading particle kind & p-tot -

• Different X-sections – different quenching...

• Jets thru equilibrized plasma-> Machshock in Plasma!

• What is the sound velocity of the medium ?

• Use jet-induced Mach-cones -> c_s of plasma !
