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 !

Jets interact in the plasma, causing wakes and shock waves relativ to jet-axis
Emission angle alpha relativ to jet axis: Cos (alpha)= Cs / V (jet)
Cs~ 0.3 in hadron matter
Cs = 0.57 for m = 0 Thermalized QG plasma
