Jet quenching: the interface between theory and experiment

chaired by Korinna Christine Zapp, Urs Wiedemann (CERN), Alexander Milov (Weizmann Institute of Science (IL)), Christof Roland (Massachusetts Inst. of Technology (US)), Marco Van Leeuwen (University of Utrecht (NL)), Christian Klein-Boesing (Westfaelische Wilhelms-Universitaet Muenster (DE)), Brian Cole (Columbia University (US))

at CERN ( 4-3-006 - TH Conference Room )
Description
This one-week workshop will focus on the interface between experimental studies of jet quenching and its modeling, including technical aspects. The main aim is to sharpen our understanding of problems at this interface and how they limit physics conclusions, and to discuss improvements. 

Open sessions will be limited to the late afternoons and they will feature mainly open round-table discussions, as well as a limited number of scheduled presentations. After an introductory session on Monday (11 Feb) that will include short presentations by all LHC experiments, the topical discussions in the following days will focus on 
i) experimental issues of jet quenching (such as unfolding, jet algorithms and background subtraction), 
ii) issues related to Monte Carlo studies of jet quenching (including inputs and defaults, the interface with medium modeling, and output/event formats) and
iii) issues arising at the interface between experiment and theory. On this point, discussions will aim at clarifying what we do and what we don't understand at present, and what is needed by the experimental and theory community to make progress. On all topics, the discussion will aim at covering not only the conceptual but also the technical level.
