Theory meets Experiment:
Theory-Experiment Collaboration for Hot QCD Matter (TECHQM)
Today is: Thursday, July 30, 2015
Scope & Purpose
The complex, dynamic nature of a heavy ion collision dictates the need for extensive theoretical modeling as the bridge between experimental observations and underlying properties of the hot QCD Matter. While good progress has been made in this area, providing essential support for interpretation of RHIC data on flow and jet quenching, there are still significant conceptual and modeling uncertainties which limit the accuracy with which conclusions can be drawn about the properties of QCD matter.
In the view of the TECHQM working group, elucidation and reduction of these uncertainties requires coherent, sustained, collaborative effort of experts in all stages of a heavy ion collision. A collaborative effort of theorists and experimentalists, aimed at systematic validation of different approaches to the modeling of heavy ion collisions, will be able to go significantly beyond the scope achievable by individual research groups, which usually concentrate on the development of models for specific collision stages. This is not an issue for the RHIC or LHC communities in isolation in our view, full understanding of the physics at both facilities will require a unified approach, to compare and contrast their results within common calculational frameworks.
The agenda of this meeting will focus on those aspects of heavy ion collisions that are at present most amenable to such a comprehensive approach: collective flow, high pT energy loss, and heavy quark dynamics. The meeting will establish the organizational structure of the TECHQM working group, and identify concrete tasks and a work plan for the near-term future. The first day will consist of a plenary session to discuss the scope and possible approaches of the working group, followed by a parallel session in which experts on each sub-topic develop a work plan. The work plans will be discussed in the plenary on the second day.
Contributed talks and suggestions for the workshop agenda are welcome.
Attendance does not imply or require membership in the working group.
