Postdoctoral researcher in experimental Particle Physics: Searching for Dark Matter in proton-proton collisions

100%, Geneva, temporary

The High Energy Physics group at ETH Zurich invites applications for the following opening in the group of Prof. Annapaola de Cosa. 

Project background

The research group of Prof. de Cosa is engaged in the search for new physics phenomena in proton-proton collision data collected by the Compact Muon Solenoid (CMS) experiment at CERN. In particular, the group is looking for signs of Dark Matter production manifesting through unconventional signatures hidden in a sea of background. The group is also actively involved in the monitoring and operations of the CMS Pixel detector, and in the study of the detector radiation damage evolution. 

Job description

The objective of this project is to search for non-WIMP Dark Matter candidates in LHC collisions by looking for partially invisible jets of particles produced in the showering of dark quarks, and hiding in the overwhelming background of Standard Model multi-jet data. The development of new tools making use of modern machine learning techniques for reconstruction and identification of such challenging signature will be pivotal for isolating DM-like data. The study of heavy-flavour enriched dark jets is also envisaged. Optimal performance of the CMS Pixel detector during the 3rd LHC data-taking period will be fundamental for the reconstruction of secondary vertices and, hence, for the identification of bottom-enriched jets.

You are expected to lead and provide original contribution in both data analysis and detector related work, and to participate in teaching activities at the ETH Zurich. The position is based at CERN (Geneva) with frequent travels to Zurich and the appointment is limited to three years with the possibility of extension. 

Your profile

For this position you should preferably have a background in high energy physics. Expertise in machine learning methods, jet reconstruction techniques, software development and detector operations are an asset. We encourage female to apply.
