Missions

Being forbidden in the Standard Model (SM) of particle physics, lepton flavor violating decays are among the most powerful probes to search for physics beyond the SM. In view of the recent anomalies seen by LHCb on tests of lepton flavor universality in b → sℓℓ and b → cℓν processes, the interest of tau lepton flavor violating decays has been greatly reinforced. In particular, several new physics models predict branching fractions of τ → µµµ and τ → γµ just below the current experimental limits.
The Belle II experiment located at KEK, Japan, has just started physics data taking, aiming at collecting 50 times more data than its predecessor, Belle, by 2027. Thanks to its clean environment and high τ+τ- cross section, it provides an ideal environment to study tau decays. The mission of this post doc will be to analyze the first Belle II data in order to obtain the best experimental limits on the lepton flavor violating decays τ →ℓℓℓ, where ℓ=e,µ. Additional decays such as τ →ℓγ or τ → ℓh, h being a hadronic system, as well as b→ sττ or B→ℓτ could also be studied.

Activities

Data analysis, participation to data taking, participation to Belle II service tasks (to be discussed with the successful candidate), activities of outreach and dissemination, students supervision.

Skills

- Ph.D. in Experimental Particle Physics
- Excellent analysis and software skills (python, ROOT, C++), teamwork abilities and knowledge of English
- Experience in Belle II data analysis is appreciated but not mandatory

Work Context

The successful candidates will be based at CPPM, Marseille, France (http://cppm.in2p3.fr)
The CPPM, which has a long standing experience in particle physics accelerator experiments, is joining Belle II in 2019 with an ERC consolidator grant obtained by Justine Serrano. The post doctoral researcher will have a key role in the group, starting the data analysis activity and supervising phD students. Travel to KEK for Belle II weeks and shifts are foreseen.

Constraints and risks

travel opportunities in france and abroad

Additional Information

Applications must include a CV, a cover letter and the names of three references who can provide letters of recommendation.

The 12-month contract is likely to be renewed twice
