Missions
The selected post-doctoral candidate will use the large LHC data set to make precise measurements of the production of pairs of vector bosons or Higgs bosons. From these measurements, constraints on the possible contributions of physics beyond the standard model will be derived, for example by using the effective field theory (EFT). To obtain the highest sensitivity, it is necessary to develop new multivariate techniques, that could include the usage of modern machine-learning techniques. The selected candidate will also contribute to the development of HGCAL reconstruction, the trigger system and/or the testing and validationof the HGCAL prototypes.
Activities
The main activities will be :
* analysis of data collected by the CMS experiment
* statistical interpretation of the data
* presentation and authoring of results
Skills
* Training: PhD in experimental particle physics.
* Programming: skills in Python, C++ and ROOT.
* Languages: fluency in spoken and written English, level C1/C2.
* Good communication skills and ability to work in a team.
Work Context
The Leprince Ringuet laboratory is based at the École Polytechnique research centre in Palaiseau. This joint CNRS-Ecole Polytechnique unit, with a staff of around 120, is involved in two areas of research that support each other both conceptually and technically: very high-energy gamma-ray astronomy and particle physics. At the frontier of technologies, these activities are developed within an international framework, with facilities spread across various regions of the world (http://llr.in2p3.fr). The LLR's CMS group is a founding member of the CMS Collaboration. The group is one of the key players in the discovery of the Higgs boson and the measurement of its properties. The group is also heavily involved in the development of the upgrades for phase 2 of the LHC.
