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 ? s?? and b ? c?? processes, the interest of tau lepton flavor violating decays has been greatly reinforced. In particular, several new physics models predict branching fractions of ? ? µµµ and ? ? ?µ just below the current experimental limits. B?(h)?? decays, where h is a hadron, could also be seen. The Belle II experiment located at KEK, Japan, started physics data taking in 2019, aiming at collecting 50 times more data than its predecessor, Belle, by 2028. Thanks to its clean environment and high ?+?- cross section, it provides an ideal environment to study tau decays. The mission of this post doc will be to analyze the Belle II data in order to obtain the best experimental limits on lepton flavor violating ? decays. If time allows, lepton flavor violating decays of B into ? lepton will also be studied.
Activities: Data analysis, participation to data taking, participation to Belle II service tasks, activities of outreach and dissemination, students supervision.

Missions: The CPPM neutrino team is strongly involved in the ANTARES and KM3NeT neutrino telescopes deployed in the abyss of the Mediterranean Sea, used for cosmic neutrino research and fundamental neutrino properties studies. The group is in particular responsible for the construction and exploitation of the KM3NeT/ORCA detector, which is under construction offshore Toulon (France) at a depth of 2450 m. This detector, optimized for the study of the atmospheric neutrino flux in the GeV range, aims primarily at the study of neutrino oscillations for the determination of the neutrino mass ordering and the measurement of neutrino mixing parameters. The successful candidate will participate to the analysis of the KM3NeT/ORCA data with the aim to take a leading role in the neutrino oscillation measurements. Activities: Data analysis, participation to data taking, participation to KM3NeT/ORCA detector construction and calibration, participation to KM3NeT service tasks, activities of outreach and dissemination, student supervision. Work context: The successful candidate will be based at CPPM, Marseille, France (http://cppm.in2p3.fr). The CPPM neutrino group, which has a long-standing experience in neutrino detection in the deep sea with the ANTARES and KM3NeT experiment, is currently responsible for the construction and the operation of the KM3NeT/ORCA detector. The successful candidate will participate to the research activities of the group. Travel to other laboratories of the KM3NeT Collaboration for Collaboration meetings, participation to shifts and eventually to ORCA sea operations are foreseen.

Additional information: Interested physicists are invited to submit their application, including a cover motivation letter, curriculum vitae, list of publications and copies of university degrees. They should also arrange for three letters of recommendation. All documents should be sent to Vincent Bertin (firstname.lastname@example.org). The review of applications will start in September 2020 and will continue until the position is filled.
The imXgam research team of CPPM is participating together with the CEA Irfu and the IJCLab in the ANR project ClearMind. This project aims at developing a scintronic crystal detector for fast timing applications in the field of gamma ray imaging. It consists in depositing a photocathode with a high refraction index directly on the surface of a monolithic lead tungstate crystal, so that scintillation and Cherenkov light extraction from the crystal onto the photocathode does not encounter total reflection. The detection of the Cherenkov light produced by photoelectric conversion of gamma rays in the lead tungstate will allow to optimize the timing performance of the device, targeting tens of picoseconds resolution by encapsulating the scintronic crystal within the vacuum tube of micro-channel plate photo-multiplier for the detection of the photoelectrons generated on the photocathode.
To assess the potential of scintronic crystal detectors for TOF-PET, the ClearMind modules will be modelled by GATE and the Monte Carlo model will be validated against measurements. For this, a pair of ClearMind detectors will be mounted on tomXgam, a mechanical bench dedicated to tomographic experimentation that will enable to acquire data in a TOF-PET configuration and reconstruct images of positron emitting point sources and phantoms.
A 2-years postdoctoral position is offered to take part to the development and to the Monte Carlo modelling of the ClearMind detectors, and to master tomographic data acquisition with ClearMind detector prototypes embedded on the tomXgam mechanical bench. This includes the commissioning of the installation of tomXgam in the CPPM imaging room and to carry out the development of its control interface under LabVIEW.
