Project description

The elementary particle physics division at Stockholm University invites applicants for a two year postdoctoral position to work on the ATLAS experiment at CERN's Large Hadron Collider (LHC). The main focus will be the analysis of ATLAS data to search for exotic heavy long-lived particles. The research will be carried out within SHIFT - Solving the Higgs Fine-Tuning Problem with Top Partners, a research project funded by the Knut and Alice Wallenberg foundation.

Through collaboration between experimental and theoretical physicists, the project aims to develop possible extensions of the Standard Model that solve the fine-tuning problem of the Higgs boson mass as well as novel ways to search for these with the ATLAS experiment. The successful candidate is also expected to perform service work in areas such as data reconstruction and detector performance.  

The ATLAS group at Stockholm University has been active in the construction, commissioning and calibration of several ATLAS detector components: the Tile Calorimeter and the First Level Trigger system and continues to carry responsibilities in these areas. The group is also involved in several combined performance groups, e.g. the flavour tagging group and Jet/Etmiss groups, as well as in the data preparation area where we play a leading role in the luminosity determination using Inner Detector tracks.

Our main research topics are searches for supersymmetry, dark matter and di-Higgs production as well as measurements in the top-quark sector. We are a part of  the Oskar Klein Centre for Cosmoparticle Physics (OKC), a rich scientific environment that comprises more than a hundred researchers working in both theory and experiment in the fields of astronomy, astrophysics and particle physics at both Stockholm University and the Royal Institute for Technology. The OKC hosts a vibrant research programme on dark matter, dark energy, transient and multimessenger astrophysics, structure formation, and related particle physics questions.

Main responsibilities

The successful candidate will play a leading role in ATLAS searches for signatures of long-lived particles. Service work for ATLAS (eg. calibration or data reconstruction) is also required, though the main focus of the position is on data analysis.
