Modelling jet quenching

Understand

High P_T measurements of hard hadrons or jets at RHIC and LHC appear contradictory and in some cases counter-intuitive, but upon closer investigation they represent a coherent picture of jet-medium interaction physics which can be established with systematic comparisons of models against a large body of data.

• This picture is consistent with a perturbative QCD mechanism and does not require exotic assumptions.
• This overview outlines how several key measurements each partially constrain shower-medium interaction physics and how from the sum of those the outlines of the mechanism of jet quenching can be deduced.
• Most current jet results from LHC can be naturally understood in this picture.
