Position as postdoctoral research fellow in Experimental heavy-ion physics isavailable at the Department of Physics.

The fellowship is for a period of up to 3 years with no compulsory work. Within the framework of the position duties may be assigned. Starting date no later than 01.10.2016.

Within the framework of the position duties may be assigned. No one can be appointed for more than one specified period at the same institution.

Job description/ Project description:

The position is associated with the Norwegian ALICE project at CERN, funded by the Norwegian Research Council. The heavy-ion group of the Department of Physics participates in the ALICE experiment, which last year entered a second round of data taking from ultrarelativistic proton-proton, lead-lead and proton-lead collisions at the Large Hadron Collider at CERN (LHC Run-2).  During this run period, ALICE aims for a precision characterization of the hot quark-gluon plasma, exploiting its superior capability in identifying particles at low and intermediate transverse momenta and utilizing rare signals, among others in the heavy flavour sector.

The candidate is expected to work on the analysis and interpretation of the data taken with the ALICE detector during the Run-2 part of the LHC programme.  The primary scientific focus of the Norwegian ALICE groups for the Run-2 period is quantitative studies of the hot partonic matter formed in the early stage of heavy-ion collisions and also of the influence of cold nuclear matter effects, utilizing rare tomographic probes involving heavy quarks, in particular charmonia. Other analysis topics include collective anisotropic expansion (flow) and penetrating tomographic probes like photons / electrons, hadrons with high transverse momenta and their correlations.

The preferred focus for this postdoctoral project would be to contribute to and undertake some responsibility within the ongoing studies of charmonium production at midrapidity, measured in the dielectron channel, now at the highest available LHC energies. Charmonium states display a complex and interesting behaviour in the nuclear medium. Run-1 data showed hints of a new quark-gluon plasma signature, charmonium production through a recombination mechanism, permitted by the higher density of charm-anti-charm quark pairs in this unprecedentedly hot plasma.  Run-2 data is expected to verify this phenomenon.

The candidate will mainly be based in Oslo, but will be expected to spend some time participating in data taking and other ALICE activities at CERN, and also to collaborate closely with members of the ALICE-Bergen group.
