The CNRS LAPP  (Laboratoire d'Annecy de Physique des Particules) laboratory is opening a postdoctoral researcher position in the ATLAS group, which aims to bring together on a common science platform new scientific findings as well as the data and analysis software of a number of collider, direct and indirect detection experiments. The position is open in the context of the ESCAPE  scientific consortium and EOSC-FUTURE Dark Matter Science Project .
The candidate will contribute to a new search for dark matter (DM) produced at the Large Hadron Collider in the final state containing two leptons in association with other objects (e.g. missing transverse energy). The goal is to make the analysis easily reproducible and re-interpretable both inside the ATLAS analysis framework and on the Open Data that ATLAS will release at the end of 2023. The combination of these results with searches for Dark Matter candidates in other final states in LHC experiments as well as with non-collider searches is also envisioned.
- Implement this dilepton analysis and other flagship DM analyses inside ATLAS within the RECAST reproducible analysis pipeline.
- In collaboration with the computational infrastructure team of this Science Project, the processed data used for the RECAST pipeline will be retrieved from the ESCAPE Data Lake, and the software pipelines will be distributed and run via the ESCAPE Software Catalogue.
- The RECAST analysis tools will be interfaced to the REANA (http://reanahub.io) CERN-hosted portal where at an initial stage ATLAS users can rerun the analysis pipelines with new signal hypotheses, and at a later stage this may be extended to external users.
- This reproducible analysis framework will be used to produce constraints on DM models that can be compared to those of other experiments with common code also running on the same platforms.
- Programming: python, C++
- Experience with data analysis in physics, preferably in high energy physics
- Fluency in English, speaking and writing
- Basic knowledge of French could be useful
- Creativity, autonomy, rigorous work
- Good interpersonal and communication skills
- Excellent writing, speaking and presentation skills in English
- Good team work skills, as the candidate will be working within a team of researchers from different DM experiments who are also implementing new analysis pipelines
Desired work experience: 0-7 years after PhD
Applicants must submit via the CNRS job portal a cover letter explaining their interest in the position and a detailed curriculum vitae (containing a description of their research experience with a list of publications highlighting their personal contributions).

Contract expected to start as soon as possible and at the latest on 01/10/2021.
The ESCAPE project is building a virtual research environment (VRE) for the Astronomy, Astro-Particle, Particle, and Nuclear Physics communities, as a prototype of the European Open Science Cloud (EOSC). It is intended that the developments of tools and services made in ESCAPE will become part of the EOSC implementation. The mechanism for that integration will be the EOSC-Future project, where science drivers are provided in different disciplines by the groups of European research infrastructures (clusters) involved in the project, including ESCAPE. A number of post-doctoral positions are available to work on these challenges in the ESCAPE partner institutes .
This project will be performed in close collaboration with the Lund ATLAS group, including periods of exchange for knowledge transfer, as well as other ESCAPE and EOSC-FUTURE project partners. The contacts with theorists contributing to the EOSC-FUTURE Dark Matter Science Project are facilitated by the presence of the theoretical physics laboratory LAPTh in the same building. The geographical proximity of LAPP to CERN  facilitates direct implication in the operation of the ATLAS experiment and communication with the research community there.
The ATLAS group at LAPP is involved in direct searches for new phenomena and precision measurements in the Higgs-boson and gauge-boson sectors as well as the upgrade of the Liquid Argon calorimeter electronics for Run 3 (2022-2024) and HL-LHC (2027+) and the construction of the new pixel detector for HL-LHC.
LAPP is a laboratory of the French National Institute of Particle and Nuclear Physics (IN2P3), a part of the Centre National de la Recherche Scientifique (CNRS). LAPP is a joint research unit of the CNRS and the Savoie Mont-Blanc University (USMB). More than 150 researchers, engineers, technicians, administrative staff, students and foreign visitors work there. The research at LAPP is focused on the physics of elementary particles and their fundamental interactions, as well as exploring their links with the large structures of the Universe. LAPP participates in experiments at LHC (ATLAS, LHCb) and FCC, neutrino detectors (DUNE, Stereo, SuperNEMO) and astroparticle experiments (Virgo, HESS, CTA and LSST). LAPP has expertise in a broad scope of domains involving innovative technologies such as micro-electronics, complex mechanical structure design and optimization, grid computing and scientific software developments. LAPP hosts a mid-range data storage and computing centre MUST providing distributed computing infrastructure for research and academic projects.
