Missions

Applications are invited for a postdoctoral position in lattice QCD and its applications to particle physics phenomenology. The fellow will be expected to collaborate closely with CPT's Particle Theory team on projects aimed at improving the computation of the hadronic contributions to the muon g-2 and to the running of the fine structure constant. While the main focus of the position is the lattice calculation of these contributions, the projects also include collaborations with non-lattice phenomenologists and experts of data driven approaches, to investigate the consistency of the lattice results with what is known via other processes or means. Moreover, the fellow will be expected to participate more widely in the activities of the Particle Theory team, as well as those of CPT. S/he will also be expected to help supervise PhD and Masters students that may contribute to these projects.

Activités

The projects will involve a variety of activities. These include: designing approaches and methods to improve the lattice calculation of hadronic contributions to the muon g-2 and to the running of the fine structure constant; implementing the resulting methods in the simulation code, notably on supercomputers with GPU nodes; extracting physical results from the raw simulation results; designing and implementing new approaches for comparing lattice results with what is known via other processes or means; interacting closely with all contributors to these projects; participating in the sharing of the results with the scientific community and more widely, when relevant.

Compétences

*) Good working knowledge of theoretical particle physics and lattice field theory
*) Independence and ability to collaborate productively
*) Solid experience in implementing complex algorithms and optimizing code on GPU architectures
*) Strong programming skills (C, C++, etc.)
*) Strong written and oral communication skills

Contexte de travail

The work will take place in CPT's Particle Theory team of which the lattice QCD group is part. The latter consists of three permanent staff (Antoine Gérardin, Laurent Lellouch, Savvas Zaffeiropoulos) and four postdoctoral fellows and two PhD students. The wider Particle Physics team also has as members Aoife Bharucha, Jérôme Charles and Marc Knecht.
The position is funded by an ANR collaborative grant with experimental particle physicists at LPNHE Paris and IJClab Orsay. The lattice work will be performed in the context of the Budapest-Marseille-Wuppertal collaboration.
The Centre de Physique Théorique (CPT) is a research unit with about 60 permanent staff and around 40 PhD students and postdoctoral fellows performing theoretical research in a wide variety of fields. Aix-Marseille U. also has strong research units in experimental particle physics (CPPM) and in astrophysics, cosmology and astroparticle physics (CPPM, LAM).
