The Institute of High Energy Physics (HEPHY) of the Austrian Academy of Sciences in Vienna, Austria’s leading non-university research and science institution, is offering a

The Institute of High Energy Physics of the Austrian Academy of Sciences in Vienna, Austria, performs a rich experimental particle physics program participating in accelerator-and non-accelerator-based experiments. The institute has a major involvement in CMS at CERN and in the Belle II experiment at KEK. An experimental group works on direct Dark Matter detection using the CRESST experiment at LNGS. A theory group completes the research profile of the institute. HEPHY is one of the founding members of the CMS Collaboration. We have been strongly involved in the design, construction, and operation of two of the major components of the experiment: the trigger system and the tracking detector. HEPHY is contributing to the high-luminosity upgrade plans for the silicon tracker and the high granularity calorimeter. HEPHY has contributed to CMS physics results since the beginning of LHC operation. One of our priorities is the CMS data analysis, in particular measurements of properties of the Higgs boson, searches for supersymmetry and the dark sector, indirect searches using rare top quark production, and measurements of quarkonium production.

We are looking for outstanding applicants with a background in high energy physics to fill a PhD student position. The position is open to candidates of any nationality that hold a Masters degree in Physics (or equivalent). Successful candidates will be invited to carry out research within a PhD thesis project at Austria's largest centre for experimental and theoretical particle physics. The working language is English.

The candidate will play a key role in a state-of-the-art search for dark sector particles with macroscopic lifetimes, such as long-lived dark photons, in rare decays of the Higgs boson or a new heavy scalar. The search will explore the signature of displaced muon pairs emerging from a common vertex in a wide range of displacements across the CMS detector using LHC Run III data.The candidate will join a team working on a related project with Run II data.

The main tasks will include the development of new trigger and data analysis strategies with the goal to maximally enlarge the reach of the search following the significant extension of CMS displaced muon trigger capabilities in Run III. The candidate is also expected to help with supervision of Master students.
