Workshop on Transport Theory in Heavy Ion Collisions (2013)

Goal of the Workshop

The goal of the workshop is to collect the current status of different hadron and parton transport approaches and to define open questions concerning e.g. the importance of multi-particle collisions, microscopic treatment of hadronization, self-consistent connection to potentials and fields, medium modification of particle properties. In addition, more technical questions in terms of implementation of the collision criterion, different ensemble techniques and their advantages and disadvantages, causality problem, ... shall be discussed.

Question to be addressed


  • Which degrees of freedom are treated?
  • Purely classical or are quantum effects treated? 
  • Are more than binary collisions treated? If yes, how? 
  • How is the high density phase treated?
  • Are resonances/quasi-particles modified by the medium? If yes, how? 
  • How is hadronization treated, if at all? 
  • Where do you see the biggest challenges for the future? 

Numerical Realisation: 

  • Which programming language? And why?
  • How is the particle list organized? Which ensemble technique is used? 
  • How is the time ordering of collisions achieved, which collision criterion is used? 

Location and Accommodation

The workshop will be held from July 15-17th 2013 at Martin-Niemoeller-Haus in Schmitten, Germany. It is located roughly 35 minutes by car from Frankfurt airport in the Taunus. Surrounded by smaller mountains like the Feldberg and nice forest we expect a great working atmosphere.  

Cost for accommodation in single rooms is: ~50 EUR per night

The hotel can be paid by VISA or Mastercard (no American Express). 

We will take care of booking the rooms for you according to the arrival/departure information provided in the registration.

Adjacent Workshop

A second workshop dedicated to our present understanding of sampling particles on a fluid-Cooper Frye hypersurface will be held from July 18th-20th 2013 at the same location. Please adjust the departure dates in your registration email accordingly, if you plan to attend the second workshop as well.
