Job description:
The theory group of SUBATECH (Nantes, France) has an opening for a PhD position for thesis of three years. In the last years we have studied the time evolution of a plasma created in relativistic heavy ion collisions using a transport theory based on the Nambu Jona-Lasinio (NJL) Lagrangian. This Lagrangian, which shares the symmetries of the QCD Lagragian, has been proven in the past to be very useful to calculate the properties of mesons and baryons in a hot and dense environment. It allows as well for the calculation of the cross sections among partons and hadrons, as well as for hadronization. Based on only a few parameters which are adjusted to static cold matter properties like masses a complete transport theory can be formulated. This is of special interest because the NJL Lagragian shows a cross over from the parton to the hadron phase for vanishing chemical potential, whereas for large chemical potentials, expected to be the region of the upcoming FAIR experiments in Darmstadt (Germany), the phase transition is of first order. The transport theory allows therefore for a study of how a finite size system passes a first order phase transition. In the framework of this thesis we want to study this phase transition. For this purpose one has to calculate the masses and the cross sections at finite chemical potential and implement these results in the already existing transport approach. The high energy-energy theory group is composed of 8 permanent senior researchers, 2 postdocs and 5 PhD students. Further general information can be found on our website http://www-subatech.in2p3.fr. Candidates should send a CV, a statement of their research interests and two letters of recommendation to Prof. J. Aichelin with whom the candidate will work. An education in the field of heavy quarks physics and/or in field theory will be considered as an advantage. For further information please contact Prof. J. Aichelin (aichelin@subatech.in2p3.fr, tel +33 2 51 85 84 09). Application deadline is 30. April 2016
