Jet modification in 200 AGeV Au-Au collisions

Understand

The computation of hard processes in hadronic collisions is a major success of perturbative Quantum Chromodynamics.

• The environment of heavy-ion collisions offers the opportunity to embed such hard processes into a soft medium which is created simultaneously and study the medium-induced modifications.
• On the level of single high transverse momentum hadrons, a reduction in yield, the so-called quenching is observed.
• However, on the level of jets, the energy-momentum flux carried by hadrons is conserved, i.e.
