The experimental high energy physics group of the Centre for Cosmology, Particle Physics and Phenomenology (CP3, website: at UCLouvain in Louvain-la-Neuve (Belgium) invites applications for a position at the post-doctoral level to join its efforts in the CMS experiment data analysis. The expected duration is two years, extendable by an additional year upon mutual agreement.

Research activity in CP3 is equally strong on the theoretical as well as on the experimental and instrumental fronts. It is conducted by 16 permanent staff members, 23 post-doctoral fellows and 25 PhD students. The main experimental collaborations include the CMS experiment at CERN, NA62, IceCube and the Virgo gravitational waves telescope. The CMS members currently focus on data analysis and related physics object software development, mostly within the Higgs, Top quark, and Exotica physics groups. UCLouvain hosts one of the Tier-2 centers of the LHC computing GRID that allows CMS data to be processed and analyzed. The group is also involved in research and development programs related to the upgrade of the CMS tracker for HL-LHC. On the phenomenological side a strong Monte Carlo development activity is present focused on the development of a wide range of tools, such as FeynRules, MadGraph, aMC@NLO, Delphes and MoMEMta. We are also strongly active in novel applications of Machine Learning in our field.

The selected candidate is expected to join the CMS experimental studies related to Higgs quark physics, building upon our experience with modern Machine Learning techniques and Effective Field Theory formalisms. The exact project will be defined with the candidates and could extend beyond these main topics. Service work (EPR) for the CMS collaboration is also expected. The Principal Investigators of the CMS-Louvain team are Giacomo Bruno, Christophe Delaere, Andrea Giammanco and Vincent LemaƮtre. More information about our CMS activities can be found at

The selected candidate will be given the opportunity to lead a well-defined analysis effort, under the supervision of one of those PIs, and in collaboration with several PhD students and postdoctoral fellows, and the analysis work will profit from close contact with the CP3 phenomenology group (Profs. Fabio Maltoni, Celine Degrande, Marco Drewes and their collaborators). It is also possible, although not mandatory, to contribute to our hardware activities, which are mainly devoted to upgrades of the Tracker system and led by Prof. Christophe Delaere, or to small non-CMS projects (e.g. Phenomenology, DELPHES developments, ML-optimized design of experiments, etc.) if they fit with the main analysis activity.

The selected candidates are expected to be based in Belgium for the duration of the contract, with visits at CERN when needed for research reasons.

Applicants must have (or expect to receive soon) a PhD in particle physics. The funding rules require that the candidates must be in the condition of international mobility, defined by our funding agency as not having resided or carried out their main activity (job, studies...) in Belgium for more than 24 months during the 3 years directly preceding the beginning of this postdoctoral fellowship, and that the PhD was obtained not more than 6 years before. Within these constraints, we strive to offer equal opportunities irrespective of sex, sexual orientation, nationality, race, colour, ethnic or social origin, religion or belief, political or any other opinion, disability, and in general any personal characteristics that is unrelated with the ability to perform high-level research. The salary is competitive and includes all social security benefits (information is available on request). The starting date of the contract is negotiable, with preference to start in October 2022. Contributions to teaching are possible but are not required. Although the position will remain open until a suitable candidate is found, interested persons are encouraged to apply as soon as possible, as a continuous screening of the applications will take place starting from September.

Applications should be submitted online (not by e-mail, please), and should consist of a cover letter (including a short research statement), a curriculum vitae, a list of publications with visible contribution by the candidate (including internal notes, proceedings, technical documents). Letters of recommendation (at least two) can be uploaded by your referees directly, after you apply.
